bike came with 13-48. Have two rides on the bike, One with 48, other with 52 rear.
48 ride was accompanied with unknowingly disconnected map switch, sun mode all along. It was tiring in slow speed and slippery long uphills were impossible.
Borrowed 52, which made transfer riding pretty high rpm-ish,bike reaches top rpm too fast, so torque rev wheelies with airborn gear changes were harder. Gnarly terrain was vastly improved, also with map switch now working, yet i'd like a compromise, so am considering 50 or 51.
Not a big help is my 2 stroke riding knowledge, especially steep slippery drive off, and a ajp master clutch in need of overhauling, waiting 4 parts.
