RAPIDO RACE 225 GEARING

[pasner]

so 15/46 or 16/46 would be good. what about the chain, should I maintain the standard one or change it? thankx.

changing the front sprocket from 15 to 16 is a big jump.
Although I've not built a Rapido Race 225 I know they are peakey. I would stick with Fishis ratio of 5.2 which for you means Li150 and 15/46 sprockets

[fishi]

again, tell us your timings and then we can tell youu something about the gearing.

The Rapido 225 Race needs a ratio of about 5.20, the JL3 you will use pulls at low revs.
