anyone have a large rear sprocket? 44+ to say 50-55 even?

Recommended Posts

My son is building his odysee and he is putting a chain drive on. He needs a large rear sprocket cause his new engine is a 6 speed. He also needs it to be for a 520 chain which I think most will be.

His new engine is a crb250r....fuel injected and then turboed on e85.

Anyways the mounting doesnt matter I have to fabricate that for him. He just needs something inthe high 40's low 50's cause I dont need him going 92 mph on the flats with a 42....

Actually no, a smaller gear on the front or a bigger gear on the rear lowers your top speed. You can verify this by a goggle search....but ive been doing this for 30 years.
