Scooterotica

Boris, I am running taffy copy,28phbh, Li150 box, 17/46. Built mine for touring hence the pipe/gearing combo. Really pleased with it but setup might not be what you are after if you are riding with rbs. Maybe shorter gearing and a revvier pipe would suit you?

I'm running an 18/47 does this mean my gear is built more for top end than yours. I'm not to clued up on it.
And 200 gearing.

Boris, it all depends how you want it to perform. If you are using gp200 18/47 (5.2) I'd guess you could pull a revvy pipe ok. Tbh i've found them all louder than the taffy though. If you aren't too sure you could always give mb a call.
