Gear ratios

I was wondering.

Does anyone know how many rpm a cl77 turns at 55-60 with standard sprockets? Vs a cb77? Do the different sprockets help mileage at all?

Thanks,

Aron

Aron,

I think I know where you're going -- if/when I finish it, my CL is not gonna be doing much off-roading, so setting up the final drive like a CB77 makes sense. After accounting for the 18 to 19 inch wheel difference, I did a spreadsheet and came up with use of a 32T rear sprocket in order to make a CL77 perform roughly like a CB77 on the street. This assumes use of a stock 15T countershaft sprocket.

Others have come up with this sprocket size, too. There have been a few posts on this subject, so give those a look, too.

Yeah that is what I am wanting to do since I don't plan on using the bike off road. I have read some other posts on it already. I was just kinda wondering if anyone had done it and their results. And I was curious how fast these bikes actually turn going down the road.
