My SH has a 42 Renthal rear sprocket. I love the way she wheelies right now. I don't know whats on the front sprocket and it also has a 520 conversion. I have read the posts on 15 43 and 16 43. Question is two fold I guess. If i remove the front cover to check and change front sprocket will I have to change the gasket? Also a little debate as to whats best for twisties maybe 10 times a year and mostly in town and hwy riding; Stock, 15-43, 16-43... Chime IN Chime IN.

OOOH, I get to be the first to chime in with: SEARCH.

J/K. Well, not really. This is one of those battered/bruised/beaten topics.

15/43 is the favorite, but you will get some different responses. It will raise your RPMs on the highway at speed. In town and in the twisties, this is the combo to go with.

15/43 yields 50mph @3000 rpm in 6th. A good compromise for sport verses commuter riding.

You don't have to replace a gasket to check your front sprocket. I like 15/43, but if your chain and sprockets are in good shape I wouldn't worry about it much.

I also like 15/43 a lot although I have never ridden with stock gearing
