The TM400 is a production motocrosser designed specifically for off-road riding. It features a tough 400 cm³ 2-stroke 1-cylinder 6-port engine capable of being ridden over the roughest road surfaces. The engine includes the Pointless Electronic Ignition (PEI) system that eliminates the difficulty of adjusting the ignition timing. Another distinguishing feature of the TM400 is its lightweight and durable aluminum rims.
