Awesome parts for my Coleman 50cc gy6 scooter. Rear clutch doesn't engage at low rpm and catches at the perfect time for better acceleration at takeoff. perfect.. I'll be using those for replacement jobs for sure.

Needs a 715 belt, my stock one was 4” longer. Good variator, good clutch. Bad beltEdit: The clutch failed only after 360 miles… the pads came off into my bell and I had to cut my belt and walk her home. Luckily was close to home… not impressed for the money tbh..
