XR650 Gearing

[GregMember]

I have been playing with some ideas for the gearing on my bike for the OBT biggest weekend out ride and found this chart, you can change the sprocket sizes and it calculates various things including top speed

With this new information I will be changing my gearing tomorrow now

For the 650 owners

shorten the gearing for the nundle ride,, you won`t need the legs of the 6fiddy up there, its lower end gearing stuff??? singles are 1st/2nd stuff

sorry

13/51 should do nice

Cheers Boony, I have 14 / 48 for that sort of thing Boony, use it in the watagans and thats more open then Nundle.

If you hit 4th on the fiddy on the trails in nundle you are flying,really flying. there openish but theres a lot of turns and intersections….
