Product Information

torque spring 1500rpm for 50cc

a stronger torque spring in your driven pulley (around 800 rmp for standard) improve acceleration, reacceleration, reduce belt sliping 

the belt stay in tension, so you stay longer in shorter speed, and high rpm, improving overall riding, even with a standard motor wich lack torque

a tuned scooter need a stronger torque spring.

available: 1000rpm, 1500rpm, 2000rpm, 2500rpm.

Attention, a harder spring shorten the belt life, prefere a quality belt like zijingang or better.

essential with a bigger bore, except for the 1000 rpm that fit well on standard motor  and the racing clutch .

Quality made in Taiwan !

Attention with the 2500RPM the belt wearing will be really very quick, the belt life is really very shorter with this one.
