rear rotor

Went to change my rear tire and surprise apparently my pads gouged my rotor. About 50,000 miles on the bike so I don't know if that is a long time or short time for a Valkyrie rear rotor????     

I don't like the price of a Honda rear rotor so has anyone had good luck with after market rotors? If so which ones?

If you have an Interstate or a newer tour there is a rotor on the classifieds. Staying with OEM is best.

Short time. I've got 150,000 miles on my Interstate, and 60,000 on my Standard. Both original rotors in good shape. Your front brakes contain most of your stopping power. Rears should be used lightly (imho).

You can clean the rotor up the best you can and keep it.

You may burn through pads a bit quicker, no big deal, but it will still help stop the bike fine. (OE pads too.)

I have a lip on this rotor. It is defiantly not smooth any more. Can you just run a grinding wheel around it? That doesn't sound like a good idea to me? How would you clean up a rotor????

I know the fronts are what is used the most in stopping the bike. I think i also have a problem with my rear caliper but I just didn't feel like dealing with that tonight. That might need a rebuild?

I rebuilt both front calipers, master cylinder and replaced the pads last year. Rotors on the front are fine. I didn't really think about the rear because it really isn't that important.


BTW my bike is a 2001 standard.

Lips on the outside edges of my rear rotor too.

More an issue with reassembly with new pads than stopping.  

I just used steel wool, no power tools.

I'm no expert.

'01 has the thickest and heaviest rear rotor of all yrs.   without pics of grooves, don't know how bad they are, however since pads are not attached to the backing plates, any grooves to rotor will not be a problem. Just clean the caliper pistons and make sure they function, and install them with new pads. suggest using DOT 4 LV, which has a higher wet boiling point and provide a firmer feel over a wider range of ambient temps.  It also extends fluid replacement from 2-3 yrs to 3-4 yrs.  not replacing brake fluid causes caliper piston corrosion and failure.
post pics of rotor if u can.

Not to derail this thread, but I remember a vender at one of the InZanes (possibly as far back one of the Michigan ones) who was turning rotors.  Does anyone know who those guys were or if they still exist? 

Maybe those guys at the InZane were a one-off, but it seems that Valkyrie rotors could be turned (once!) and used as long as stay within tolerance.
 
Had my blinker on across three states!

     Should use a micrometer and see what the tolerances are for your application. Any good auto machine shop should be able to turn your rotor. RIDE SAFE.

For anyone interested. The end result is I'm going to rebuild the rear caliper, parts a coming. New brake pads and I'm going to try to sand down the rotor a little bit. The grooves aren't that bad so I'm not all that worried. Parts won't be here till this weekend so I'm calling around today to see if any brake shops will turn motorcycle rotors. If someone can do the rotor I will do that but I don't live in a place with a machine shop anywhere. Tire and brake places yes but I bet they don't do rotors any more. Just sell new ones.

I would follow the advice given of scuff or sand rotor lightly and install new pads.

Keep a eye on them for the first couple of rides, then forget it.

Just under $23.00 per set, pads are cheap. Rotors are not.

Good pads for $23?  Share the source.  What I see is either OEM expensive or too cheap to consider.  A lot of us would be interested in a quality item at a reasonable price.

This is to put Interstate rear pads on the front and rear of any Valkyrie?  (The link didn't work on my computer.)

Sorry, on my computer that link does not lead to $23 brake pads.  Can you tell us what they are?  Rocky Mountain does sell OEM pads at $53.64 a pair.

He is referring to the rear pads.

Edit; I just noticed the Standard pads are listed at $53, and the Interstates are at $23. I'm not sure why, I believe they are the same.

Interstate rear pads may be so low in cost because they are still original inventory and never re manufactured.

IDK, but my experience is with modification the IS rears pads work in all Valkyrie calipers.

Most automotive parts places cannot turn a motorcycle rotor.  The issue is that the MC rotor's center hole is way to big to fit into a standard turning machine.  HotGlue made an adapter to bolt to the rotor that has about a 2.5" hole in the middle. This allowed the machine to be able to clamp the adapter in the machine and rotate the machine slowly to tap the rotor in line.  Then, just finish tightening the bolts and turn the rotor just like a car/truck.
HotGlue (Mark Baker) makes things like this all of the time.  Just sayin'.
