Heya, Probably a ridiculous question, how to determine what rear sprocket's will fit on a FZR 250 3LN?
dont know dude, if you want custom sprockets thrustcompany in the us will make u font, rear and chain for about $220
http://www.jtsprockets.com/61.0.html?&L=nkommvwzrmq JT Sprockets has an amazing only catalogue, with cross-referencing to different models.
JT sprockets catalog is great, but ordering their sprockets might be a different matter. I am trying to get the stock 17 front and so far the dealer has a problem to get any commitment day from the distributor. That is in Canada, your mileage might vary depending on your location. I'll end up ordering one from wemoto.com even though the maker is unknown.
Haha, i got told for a 60+t rsprocket ill need 2 chains, i just ordered a 17t fsprocket for $18 lol from bikebiz.com.au
