Look back at the picture I posted. It's a 2 piece rotor that flexes at the round looking rivets (theres 10 of them) also known as floating. This allows the rotar to allign itself in the caliper during braking ensuring full contact of braking surface.
It's really not nessasary to have floaters on a Harley whereas this is more designed for performance type bikes, but as the story goes if it's better, get it!

 

When you do the exchange with ***** Shiny, what do you get back, a brand new, polished rotor, or a used polished rotor?

Does HD sell new, stock polished rotors?

Thanks

 

Joe(owner of ***** Shiny) is very picky about his rotors and will give you back a used one that is polished to an unbelieveable shine, and no I don't work for him either.

Many try to send him crap and he will not do the exchange if they are warped or too far out of true.. and yes they determine that.. best bet is to call him.. He'll tell ya..

 

There are probably no chromed oem(stainless) rotors out there. Most likely all you see are just polished. No polished doesn't stop as well, either dry or in the rain. Not a huge difference but it's there.

 

They are for heat expansion, non floaters will warp when they get hot hot, stainless rotors suck ***** at shedding heat. Stainless floaters won't shed the heat any better but they are more warp resistant as they can expand with no constriction. No, the floating action doesn't help braking power or alignment.

 

Gotta love this place! Glad to learn of ***** Shinny's, thanks! I'll be getting to ready upgrade my front end real soon.

Anyone familiar with any others that exchange parts like calipers etc?

 

I have chrome on one bike and polished the other one's myself. To polish it spent the afternoon with the rotors removed, various grits wet/dry sandpaper, an electric plam sander, and a six pack. After I got them shining pretty well I went to a truck stop and got some polishing rogue and finished with that on a buffing wheel attached to an electric drill.

 

I What maintenance is required to keep a polished rotor looking good?
Thanks

 

I don't do anything to mine. Just wipe it with a cloth.
