You will not be disappointed with this KOSO clutch and Bell set up. Stage6 uses the same Bell and designed their MK II after this clutch. So many ways to set up and the the wheel off the ground.

With a 70cc kit this clutch and bell set up along with 19mm carb, 70 pipe, 2000RPM torque spring and 4 gram weights you will get huge top end and so much bottom it hard to explain. It Just Works.

Great set up that gets the job done for two stroke scooters using the 40QMB engine which is all chinese models including QJ and Jonway.

Kit is also top notch for Yamaha ZUMA and Quads using Jog engines 70cc and 90cc

Adjustable for fine tunning.

Koso parts are Stage 6 also just different names,
