Vortex sprockets
 

I'm trying to order the rear sprocket from knee draggers and I hit a snag. I want the black coated one but they don't have that option even though they show it. Will the 03-06 RR rear sprocket fit a 2002 f4i?

ive looked around at sprockets a lil and from what ive seen you can only getthe vortex black ones for the f4i if you do the 520 conversion. dunno if thats what your doing anyways. as far as the rr sprocket i dont know.

rr sprocket won't work

RE: Vortex sprockets
 

the F4i and RR both use 252-xx (xx = number of teeth) Vortex sprockets for standard 525 sprockets (521A for 520) BUT they still show you can only get the 520 sprockets (again 521A for both F4i and RR) coated, so point is you can only get the coated sprocket if you do the 520 conversion (you could try calling vortex though, they might can do something)
