Best? That's subjective. I have Vortex spools and they don't require any sort of washer.
I have the spools that came with my rear stand, and i had to use a nylon washer that i painted flat black to ensure the spool wasnt rubbing against the frame on the right side. On a 2008 600rr BTWsometimes the right spool needs a washer.
Can you use axle sliders with a rear stand? And how it the instalation?yes 8mm-and get woodcraft if you have budget.
BUT these spools DO NOT do much in the way of protection.
and can damage swingarm if unlucky.
Axle sliders =better protection.
That is pretty common with spools on out CBR's.like an earlier message said, the spools offer no protection. i went down last night and the spool and the metal thread the spool screws into got completely ripped off the swingarm.
Hmm I have yet to feel a heavy spool. And how do the look snazzy there are slider spools and regular spools other than that almost all of them look the same.Plus there small, lightweight and look snazzy!
