Hey all,
I have a GR650 I just build into a neat little cafe style bike. Only thing is, I find it revs high as hell to go highway speeds. Redline starts at 8000, I find i am pushing 5500 - 6000 to go 110/120 km/h on the highways. The stock gearing is a 15 tooth sprocket up front and a 42 tooth sprocket on the rear. I've seen 16 tooth fronts available from PBI and 38 tooth rears available from JT on ebay. Would getting both of these be overkill? I think knocking the RPM's by about 1000-1500 at highway speed would be ideal. I find first gear is barely needed and I am ready to shift into 5th at 70km/h.
Does somebody who knows how to do the bike math have any reccommendations for me? This is my first chain drive so not really sure what works. Thanks!
