Wanted! 48 tooth PN and OD?!

[FinalImpact]

Wanted: 48 tooth rear steel 530 sprocket part numbers!

Ya, so I set out to find a name brand rear sprocket of 48 teeth and get the new outside diameter (OD). Should be a 15min task but noway...

Chain and sprocket look great at 18,XXX miles but I wanted to try something different.

46/16 = 2.875
48/16 = 3.0
46/15 = 3.066

They list a 48 (RFE479:48 black) but their site is confusing so give them a call....

Yes! I actually stopped by their place a few months ago and bought a whole kit. Chain and 2 sprockets. I bought the hybrid steel and aluminum for the rear.

Good guys and they gave Lisa and I the cooks tour...

Here ya go,:thumbup:
part number JTR479.48T
Got it off the Old Bike Barn.
Also learned Fz1 sprockets are the same!:rockon:
For the OD,could you take pitch of chain and multiply by number of teeth?
It would get you close.

Thanks!
Had to do a little digging to confirm its 530 and it is!

FWIW: our rear hub is used on allot of yamaha's R6, R6s, FZ1, and maybe R1. Have to dbl check that last one!
