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. For 2019 the engines have had a total re-design and feature multitude of new and exciting additions to increase performance and ease of use for the rider. Whilst retaining many well proven internal components, from the exterior, the engines have a whole new look and share little in cast components with the outgoing engine. The complete re-design has been produced to accommodate numerous changes, changes that include electric start on all models, alongside a fuel injection option on EN models with a digitally controlled oil distribution system, whilst carburetors remain on the MX / SMX / FT models. A revised gearbox assembly also features, with friction reduction coated and treated parts to ensure smooth and precise shifting. We also have the addition of a balancer shaft to reduce 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, which also features a new operational control system, that will see the servo mounted to a new cylinder and working directly to a new pulley system. Revised 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), ensuring the best power delivery and traction at all times. 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, giving the best in traction 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.
