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 .

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