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. The settings utilised have created a chassis with great response to terrain changes, improving tracking and rear wheel traction, this in combination with the confidence inspiring ‘over-sized’ braking system that works, and keeps working in the harshest conditions, gives 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, a 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 new exhaust system, all fed by a Keihin 28mm carburetor 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 to the cylinder arrangement and port timing, it will continue to adopt all the previous model revisions, which included a new crankshaft, running on new reduced friction main bearings, alongside new crank-seals designed to ensure increased seal durability whilst reducing frictional losses. The cylinder received a new configuration and port timing arrangement to maximise performance throughout the rpm range, when combined with the twin-blade power-valve system and once again give a better overall power delivery. A revised exhaust system features alongside some small ignition changes to harmonise all the changes to give one of the best 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, new Mupo Race Fork, Extreme Tech shock absorber, TM even felt the need to include a built-in hole-shot device, the specification is endless. For 2020 the aesthetic look of the machine will remain the same with its already modern design replicating that of its big brethren, albeit for a new decal scheme incorporating some brighter colour accents giving 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 the after-market, an excellent package of high performance, superb handling characteristics, light weight and excellent reliability for the youth sector.
