OK for racing!
Suits 50cc Yamaha and Suzuki 2-stroke scooters. Also fits most Yamaha 2T 80cc, 90cc and 100cc and clones.
This clutch spring is the lightest of 4 upgrade options - slightly stiffer than most standard springs.
This can be used to stop bogging of the clutch caused by old sagging springs, reduce belt slip, and also helps keep RPM higher during acceleration by slowing the rate that the variator moves the belt. Additionally it improves "re-acceleration", the characteristic which means the transmission is in a lower gear after slowing down and then reapplying the throttle.
Fits 50cc Minarelli:
Adly SF-50 Silver Fox, GTC-50 Gatecrasher, RT-50 Road Tracer, GTA 50
Bug Jive, Malaguti F10, F12
CMG SS50, CPI, Keeway, VMoto and FYM Urban scooters plus Yamaha 50cc Jog, Vino etc and clone 90cc 2 stroke, 100cc 2 stroke.
Note the 50cc spring is considerably softer than the 90cc and 100cc spring, Kitaco version for much stiffer option for those bigger engines.

TR50 Street Magic, AZ50 / Let's, Let's II
