Adjust the transmission of your karting with a millimeter precision thanks to the TM KART official box output gear. Mistress of the secondary transmission of your 125CC gearbox engine, this gear is installed directly on the box output shaft to drive the string to the rear crown.

Machined in high quality carbon steel and then subjected to heavy thermal cementation, this original gear resists traction constraints, transmission shocks when changes in reports on the fly and premature wear. Its teeth cutting at 428 guarantees ultra-fluid chain flow, limiting friction losses and ensuring you from 100% of the engine torque to the track.

Available in a wide range of teeth (from 14 to 20 teeth), it allows you to ideally calibrate your demultiplication according to the characteristics of each circuit (winding track requiring racking or quick drawing requiring high peak speed).
