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 will received new cylinder configurations and port timing arrangements alongside new cylinder heads. A revised exhaust system also features with new Cdi programming and settings all designed to maximise the performance of the engine alongside a new TMEES electronically controlled exhaust valve with a direct drive system like it bigger bretheren. This new arrangement 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 variants fuel injection will also feature and includes a host on new engine changes specific to these models, including a new crankshaft and a whole new electrical system dedicated to the TSi injection system.
