SINFONIA ‘RR’. ELECTRIC-MTB

MODEL RANGE PRESENTATION


The world renowned Pesarese manufacturer has once again taken its exceptional range of motorcycles to the top of the world stage in many disciplines, competing against the much larger manufacturers with their ‘limitless’ resources. TM Racing have taken world, European and domestic championship titles throughout 2022, all whilst abiding to their own philosophy of using their handcrafted, high specification, high quality and high performance ‘customer’ machines to do so, not with ‘one-off’, specialist machines that are far removed from the production models. Dealers and customers alike have also added a multitude of national and domestic results to their tally throughout the TM Racing network globally, with both 2-stroke and 4-stroke machines in various classes structures and disciplines.

TM Racing’s exceptional quality remains as always, built to perform at a level in standard trim, far beyond what is the conventional expectation. Greater performance throughout, not just in power, but in delivery and control, improvements in handling in all terrains with chassis and geometry revisions, combined with real ‘wet’ weight reductions. Technological advances in fuelling systems, updates and improvements to engines and ancillary components, all working to achieve better mass centralisation and handling, especially on the 4-stroke machines with their naturally heavier engines. TM Racing have created some of the lightest ‘ready to ride’ machines in their class, true performers and motorcycles built to race from the offset, what we have all come to expect from a TM Racing machines.

The latest generation of the TM Racing range has been given numerous beneficial updates in many areas throughout the 2-stroke and 4-stroke range, with a number of changes and some unique technical innovations once again, As is now customary, all achieved using the TM Racing philosophy of ‘’we build it how we want it to be built’’, not working to a ‘budget’ or making sacrifices where none should be made. A philosophy that leaves many dumbfounded as to how TM can produce what they do, in the volume they do, for the consumer price.

For the new model year the TM Racing range will be further enhanced with some small but beneficial changes, adopted throughout the full model range line-up. These include updates and revisions to engines an ancillary components, changes to fueling / electrical systems and revisions to the chassis set-up. TM Racing’s latest generation aluminium chassis – that was new for 2022 and achieved great improvements in structure / flex, handling characteristics, a reduction in chassis weight for every model across the range and allowing for better rider positioning and freedom of movement, remains for the new model year. Each ‘capacity class’ and designation of model machine also features its own chassis for both the engine type and in some cases, model discipline, all designed and engineered to work together harmoniously to further enhance an already excellent range of motorcycles.

With a multitude of exceptional materials, quality machining, processing, and material treatments, that are seldom seen on the inside, matched to a huge number of machined aluminium and high-quality parts on the outside, TM Racing motorcycles are constructed to a near ‘factory’ machine specification list, albeit designed for the retail consumer. TM Racing ‘factory’ bikes have more in common with their production counterparts than would ever be believed. The TM Racing ‘factory’ machines run the same components as the bikes they produce for their customers. Yes, some new parts and settings are applied for testing, developing, and of course improving their production models, but never ‘exotic’ parts or materials that would never feature on a production machine or in a future catalogue or model year. A great testament to the TM Racing philosophy and the build quality, performance and strength of their stock parts, stock parts that others must sacrifice to achieve their goals. In short, TM Racing ‘race’ their machines at the very top of our sport to allow them to design, build, test and ultimately, produce bikes for ‘you’ that can compete at the highest levels.

MX 85 Junior – Small Wheel 14″ / 17″ – Big Wheel 16″ / 19″.
TM Racing MX 100cc & ‘NEW’ 112cc Junior Machine Also Available.


The 85cc / 100cc / 112cc machine receives some small but significant technical updates for the new model year, all designed to further enhance an already incredible package. With a growing reputation of being one of the best ‘out-of-the-box’ 85cc machines on the market, the TM 85 MX machine has an ever-increasing track record of excellent results and great reliability. With a chassis that not only gives superb riding characteristics but is also one of, if not the, lightest on the track in real world terms, matched to an engine that has a great spread of usable, class leading power. The smallest machine of the TM Racing brand range is constructed with not only performance in mind but also durability and is well received by amateur and professional alike in its characteristics.
The aluminium chassis, a first for a ‘Junior’ model, not only looks incredible but also delivers the lap times when matched to the ‘factory’ type fork and shock absorber arrangement. For the new model year the aluminium frame has seen some small construction revisions, likewise small revisions apply to the suspension configurations (including an ‘optional’ front fork) and the settings utilised create a chassis with great response to terrain changes. Improvements in stability and rear wheel traction combine with the confidence inspiring ‘over-sized’ braking system – that keeps working in the harshest conditions – to give a great chassis package of tried and tested components. Built to perform and keep performing whilst maintaining lightweight and retaining ‘upmarket’ componentry and strength throughout, the TM 85 MX is an incredible machine.

The 85cc water-cooled, power-valve type engine features a billet machined crankshaft, a machined and ‘treated’ con-rod, hand finished crankcases – that feature a water jacket around the crankshaft area for reducing crank temperatures,  V-force reed block, hand finished cylinders, an ‘oversize’ gearbox and clutch arrangement – for superb durability and ultra-reliable clutch performance, die-cast clutch casing and ancillary covers for a smooth look, lighter weight and superb strength, a Kokusan ignition system and Scalvini exhaust system, all fed by a Keihin 28mm carburettor with an oversize intake bell mouth, breathing through a large volume Twin-Air air filter.

For the new model year, the already outstanding 85cc engine will see only minor changes and revisions, it will continue to adopt the previous model year specifications changes which included a new crankshaft running on ‘friction reducing’ roller main bearings, new crank-seals designed to ensure increased seal durability whilst reducing frictional losses, alterations and weight reductions to the gearbox and a new clutch basket fixing system. The cylinder continues to adopt the latest updated configuration and port timing arrangement that was designed to maximise performance throughout the rpm range when combined with the twin-blade power-valve system revision and port shapes. All these changes are of course harmonised with the ECU ignition settings to give the best overall power delivery and create one of the highest performing engines in its class. Chassis components include, billet triple clamps, billet hubs laced to excel rims, billet rear brake lever, oversize brake discs with oversize calipers, braided brake and clutch lines, hydraulic clutch, Mupo / Tech Race Fork, Extreme Tech shock absorber, the specification is endless. For 2023 the aesthetic look of the Junior machine will remain the same, replicating its bigger brethren in many aspects. The adoption of a new decal scheme, incorporating some brighter colour accents, will give a more striking visual appearance. A machine built with purpose, using some of the best components and materials available, designed to perform and keep performing without the need to invest heavily in after-market parts or tuning, giving an excellent package of high performance, superb handling characteristics and light weight, with excellent reliability.

The legendary TM Racing 125cc and 144cc 2-stroke engines are synonymous with performance. Combined with some incredible technical innovations, the latest evolution of engines are designed and constructed from some of the best materials and feature some of the best ancillary components available as standard fitment. TM Racing have created small capacity engines with outstanding power characteristics, greater than their actual capacity would suggest, alongside superb reliability to give class leading performance from the outset time and time again. Both the 125cc and 144cc variants have received small, but significant, revisions for the new model year in terms of engine set-up. These new changes work alongside updated electronic programming designed to maximise the performance of the engine in all guises. The TMEES electronically controlled exhaust valve with a direct drive ‘rod’ system remains, a well-proven and reliable system which was a welcome update to these small capacity engines. The ‘direct-drive’ TMEES system gives better response with a gain in power/torque at the lower range whilst strengthening the mid / top end performance of the engine. The TMEES system electronics have been profiled to work seamlessly with the engine electronics to ensure power, torque and responsiveness is always at its best for each given discipline. On the 125cc / 144cc EN and SMR ‘Fi’ variants the new TBi fuel injection systems will feature a host of new changes specific to these models.

The large capacity TM Racing 250cc and 300cc 2-stroke engines are synonymous with strength and durability, with each capacity engine having its own unique qualities in the terms of performance and power delivery characteristics. In 2019 the engines had a total re-design which featured a multitude of new and exciting additions to increase performance and ease of use for the rider, these engines were then updated once again in 2020 for the release of the fuel-injected variants, these changes remain and are adopted across all models. For the new model year we only see some small changes and revisions to these already ‘complete’ engines, including new crankshaft tolerances, revised cylinder ports and a new balancer shaft bearing set-up. There are also updates specific to the ‘Fi’ variants which include alterations in the fuel injection control system for better performance.  

Whilst retaining some internal components, from the exterior, the latest generation engines have a whole new look and share nothing in terms of cast components and little in internal components with the previous class engine that was phased out in 2017. The complete re-design of this latest engine was born and produced to accommodate numerous changes, changes that include electric start on all models, alongside a fuel injection option on ‘road’ models with a digitally controlled oil distribution system. The gearbox assembly also features friction reduction coated and treated parts to ensure smooth and precise shifting and a whole new gearbox assembly for the Enduro variants featuring 6 ratios (option on carburettor models). The recent addition of a balancer shaft reduces engine vibration, giving smoother performance, better ‘feel’ and a reduction in rider fatigue. The gear position sensitive ignition works alongside the TMEES exhaust valve control system, with the servo mounted to the cylinder and working directly to a revised pulley system. Electronic control programming, alongside the handlebar mounted twin ignition map switch, allows the power delivery for each of the 250cc and 300cc engines to not only be tailored by the rider on track, but the electronic systems also make alterations to the mapping depending on gear selection, valve position, rpm (and communication to the fuel injection system where applicable), always ensuring the best power delivery and traction. A system that is proving to be great for the hole-shot and those slippery rock sections alike, depending on machine and discipline of course, thus allowing the engine and control systems to give the rider the required power and torque at the required time to give the best in performance in all conditions. Constructed from some of the best materials for maintaining performance and reliability these already class leading engines that produce incredible, yet usable, controlled power and torque combined with quality ancillary components, have taken themselves to a new level. Power delivery, rider comfort and ultimate outright performance is optimally tailored in each discipline in all conditions in a way never seen before in off-road 2-stroke engines.

The TM Racing range of 4-stroke engines has become legendary for exceptional power delivery and outright performance and durability. The ability of these engines to perform has become renowned worldwide and for a ‘production’ engine the internal components and materials used are unmatched, many of these components and materials being of a level of quality that would only usually adorn the best of the ‘factory’ engine machinery. With an ever-growing list of results globally in many disciplines, the 4-stroke range of TM Racing engines has grown to not only accommodate the off-road sector, but also now feature in road racing and even Karting. The smaller capacity 250Fi / 300Fi engines have been dominating in the Enduro world for several years, taking multiple world titles, European and domestic titles around the globe. Likewise, the 250Fi / 300Fi MX and SMX variants are adding to the trophy cabinet tally. TM Racing’s larger capacity 4-stroke motorcycle range has seen great success over the past seasons, with the SMX (SMK) 450Fi machine now having taken multiple Supermotard World Championship and domestic championship titles. 2022 has been no different and once again the latest ‘SMK’ 450Fi version is leading the way, taking yet more World and European Championship titles this year. Held in high regard, the SMK is the bike to be riding in Supermotard to get the desired results, this machine has been designed and built specifically without compromise. A bike that can be bought as a package, ready to thrive in this discipline, where others are generally adapted machines created from other MX base models, the SMK 450 is proving unstoppable as did the SMX version before it. The 450Fi Enduro model was also recently adopted and developed to form the TM Racing Rallye bike, the 450 DKR / Rallye, a machine that has taken world championship victories in its class, a great testament to performance and durability in the harshest conditions. The 250Fi and 300Fi variants are also currently setting the world stage alight and have taken many World titles in the hugely competitive World Enduro Championship. These latest TM Racing 4-stroke machines have been turning heads and impressing riders globally with their sheer performance and handling, a superbly engineered racing machine that are outperforming their predecessor in all aspects and achieving great results.

The 4-stroke range will retain the current ‘reverse’ chassis configuration with fuel tank under the seat and the air intake above the engine. This layout has seen a huge transformation in the handling characteristics of all the 4-stroke models since it was introduced and has been gradually improved upon year on year. Centralised mass, better outright balance and revisions to the geometry and suspension settings have allowed TM Racing to create and incredible range of 4-stroke machinery all with superb ability and agility. An incredible range of engines matched to an incredible range of chassis, each tailored to a ‘base’ engine, have given TM Racing the ultimate range in 4-stroke machinery, with each model proving itself to be class leading on the world stage in it’s given discipline. We have some small but significant changes to the engines for 2023, alongside a new engine for the MX 450Fi model, all model variant engines differ internally on a large scale also, differences to the camshaft, piston, valves, crankshaft, con-rod, gearboxes and more, not to mention settings in the electronics and fueling systems to tailor the performance of each engine perfectly. Each of these changes is tailored to every model and designed to work alongside the revised throttle bodies and Fi systems, maximising the responsiveness and outright engine performance of these already incredible engines for each given discipline. The legendary 450Fi engine, that has dominated in its Supermotard guise for over a decade, seen huge changes in 2022 with the release of the ‘twin’ pipe engine ‘SMK’ model – akin to its smaller capacity brethren, that featured a revised cylinder head with two exhaust systems and a finger follower valve train. This engine design will now be defined as the TM Racing 450Fi engine of choice in terms of performance and thusly we will now see a revised variant in the MX 450Fi machine. All 4-strokes models will receive some technical changes for the new model year, all designed to work harmoniously to give greater performance throughout. The best just got better.


CHASSIS SPECIFICATION:

The high-end specification of all TM Racing machines is well-versed and this model year is no exception. The specification list for a ‘production machine’ is vast and features numerous high-quality components throughout. For the new model year we have several small changes and revisions to further enhance the ‘new for 2022’ chassis that was already designed to improve handling, weight balance, overall machine weight (reduced), rider ergonomics and the visual look. All variants chassis’ and sub-frames will once again be constructed using aluminium, with each engine ‘capacity’ / variant having a chassis unique to that engine displacement. This ‘tailoring’ of the chassis to engine allows TM Racing to design and build each machine for minimal weight, compactness, and better handling characteristics with mass centralisation specific to each model whether 2-stroke or 4-stroke. All chassis are constructed using the latest design elements that reduce overall chassis weight whilst maintaining maximum strength, matched to new revisions in chassis geometry / triple clamp angles that are specifically tailored to each model once again, allowing the best in handling characteristics for each model in the range. On all models, the now standard fitment KYB 48mm twin chamber fork, will continue to adopt the latest generation of internal friction reduction ‘coatings’ with some revised settings from 2022. These latest generation forks are designed to give improved response for faster changes to the terrain, all still controlled by the more favourable spring and oil set-up which is still proving to give greater reliability and more consistent performance.  The TM Racing shock absorber, made in house by the TM racing technicians, has seen some large internal changes over the last 2 years and will still adopt this latest ‘seal’ system designed to reduce friction and increase shock performance. Combined with the latest swing-arms, linkage components and spindle diameters to limit and ‘control’ flex, the shock allows for a more progressive feel, giving improved track stability and maximising traction. The chassis and suspension components work together to achieve incredible handling characteristics on a multitude of surfaces, allowing for greater stability in all conditions, increasing traction and inspiring greater confidence to reduce lap-times. The aesthetic look of the machines will remain as per 2022, where the latest chassis generation is not only ‘form’ but ‘function’, reducing the width of the bike reduced by 3cm to create a slimmer machine with better rider ergonomics and more freedom of movement. The current appearance of the latest generation model range is still one of the most striking to date, a mix of angles and curves that blend seamlessly into each other from front to rear. Beautiful, yet aggressive in its shaping, the body panels will feature a new decal scheme for 2023 incorporating some brighter colour accents giving a more striking visual appearance.

‘FRESH AIR SYSTEM’: All TM Racing adult 2-Stroke models feature the ‘Fresh Air’ intake system which allows the engine air filtration system to breathe cleaner air, this system reduces particulate contamination of the air filter maximising power for longer duration. Air is channeled from the intake vents –  via the radiator panels and fuel tank –  to the airbox which houses a large volume air filter. The ‘Fresh-Air’ system also brings another added advantage in the form of a lower centre of gravity, with the fuel tank now positioned slightly further into the chassis around the engines cylinder, this ‘weight’ shift, combined with the latest frame geometry and suspension, all work harmoniously to maximise the handling characteristics of each machine. The 4-Stroke machines also continue with ‘reverse’ layout, which sees the fuel tank moved under the seat area whilst the engine intake and filtration system is now positioned above the engine. This allows the 4-Stroke engine to breathe cleaner air with a much more direct air feed into the Fi throttle body, filter contamination is decreased whilst engine performance and response is maximised. This chassis layout witnessed a huge transformation to the complete range of 4-stroke model machines, with the centre of gravity lowered further into the chassis, especially when noting that each capacity model has its own main chassis unique to a specific engine base. TM Racing have created a line of incredibly nimble and agile machines, better handling characteristics, turning, stability and weight losses were seen throughout the current chassis guise as well as gains in engine performance.

WHEELS: The CNC machined billet aluminium hubs, laced to anodized Excel rims, feature the latest spoke arrangement with a ‘tapering’ design profile in a stronger material, a material treated to increase corrosion resistance, larger spoke nipples feature on the front wheel also for added strength. The wheel configuration allows for the best in strength and durability of the wheel components whilst reducing the un-sprung weight by a small margin. The CNC machined hubs, featuring external dust seals encircling CNC machined wheels spacers to further protect the wheel bearings, are mounted to the suspension components via large diameter hollow spindles. The larger diameter spindles, machined through their centres to lower weight, allow for a more rigid fixing off the wheel reducing the flex and allowing the suspension to work more effectively.
BRAKING SYSTEMS: The braking systems for the TM racing model range has also received some new components in the form of some new options for the SMK range and new Brembo front brake pumps for some adult models. The entire model range continues to feature high quality oversize wave discs working with TM Racing’s ‘mix’ of components. The master cylinders are connected to the brake calipers with lined and braided high quality racing brake lines that are designed to minimise expansion and ensure maximum braking effort is always transmitted to the calipers. This tried and tested collaboration of parts is regarded as one of the best braking systems in many tests and by racers alike. These braking systems keeps performing in the harshest conditions giving great efficiency and inspiring confidence always. The rear brake system is actuated by a twin bearing pivot-mounted, billet machined aluminium foot lever with a replaceable tip.

TRIPLE CLAMPS: The triple clamps fitted to TM Racing motorcycles competition range are CNC machined from block aluminium and each clamp is a work of art. The clamps intricate machining, most of which can only be seen from the underside, gives a structure designed to be supremely strong whilst keeping weight to minimum. The triple clamps also come with an optional ‘damped’ bar mounting system that through a tapering rubber cone arrangement, allow vibrations that can be transmitted through to the handlebar area to be reduced, whilst also allowing some ‘give’ to the bars in the event of a fall reducing the chances of more severe damage occurring to the handlebars and the components adorning them. The handlebars are secured, via the optional ‘damped’ bar mounting system, by billet machined bar clamps, with the top bar clamps featuring a machined TM Racing logo on their upper face.

CLUTCH ACTUATION: All TM Racing machines come fitted with a Hydraulic actuated clutch as standard, the master cylinder, made by Brembo, transmits fluid via a lined and braided hydraulic line to TM Racing’s own ‘slave’ cylinders. With separate slave cylinders for the 85/125/144 engines, the 250/300 engine, the 250Fi/300Fi engines and the 450Fi and 530Fi engines, each unit designed to fit and perform for each model giving a balanced clutch feel between all engine size variants, with both single and dual seal pistons in the slave cylinders depending on model application. The Brembo master cylinderS, working with the braided hose that limits hose expansion under extreme load, gives great feel and precise clutch control with great durability when combined with TM Racings ‘cush-drive’ (hard coated) clutch baskets, which on all variants 250cc and over, are coated with a hard wearing, friction reduction coating. All clutches are multiple disc ‘wet’ units with multi sprung pressure plates.

ELECTRIC STARTING: The ES abbreviation in any motorcycles descriptive from the TM racing range denotes that the machine has ‘Electric Start’. The TM Racing Electric start system is powered by a new, lightweight, Lithium-Ion battery that is recharged during engine running by the electrical system. Electric start is now standard fitment on all models and engine capacities over 144cc.

ENDURO / ROAD EQUIPMENT: All Enduro and ‘Road’ designated variants of the TM racing model range come with a full, self-generating ‘LED’ illuminated lighting system (which can operate also from the battery system on Electric Start models) powered by the crankshaft mounted electrical generator. This system includes a complete ‘side’, ‘dipped’ and ‘main’ beam headlight assembly – AHO specific, a rear taillight and rear brake light – operated by both front and rear brake actuation cylinders – with rear number plate illumination, a turn signal ‘Indicator’ system and of course, a horn. All these functions are controlled via a handlebar mounted multi-switch that also includes an ‘engine stop’ button. Working alongside the lighting part of the system is an illuminated digital speedometer with ‘trip’ functionality, this speedometer unit registers the vehicles given speed via a sensor located on the rear wheel of the motorcycle.
