If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

I was looking to convert my GS 450 to a 520 chain sprocket set.

I found some front sprockets that will fit the bike, but I cant seem to find any rear sprockets.

Does anybody know the BCD (bolt center diameter) of the rear sprocket on these bikes? And / Or where I could find a 520 rear sprocket for this bike?

Thanks!
 
I have a 42T with 2k miles on it that is GS pattern if that's of any use... Had it on my 750 but switched it out for a bigger one.

It's a JT sprocket & I ordered it from Z1 Enterprises. Sure they could sort you out with a new one too... give them a call :)

Thanks! That site gave me the right measurements I need. Now to find a 520 set...

And the 520 chain conversion cuts down a huge amount on rotational weight and provides better acceleration.

I wen from a 525 to a 520 on my CBR and noticed a difference immediately.
