another great project from a friend, who is building an S90 trial bike.
And I will so lucky that I get to work on some little things for this bike also.
- C110 race camshaft
- 17x1.20 (1.40) shouldered rim (DID)
- (copy of) RSC90 fuel tank
- RSC 90 gearbox (parts)
if you want to know more? Or if you have tips on RSC let me know at
