Well my  20 year old front rotors are pretty much done. They're actually a few thousands under the 4 mm minimum. I kind of cringe at the idea of replacing them, I know it ain't going to be cheap, but does anybody know a good source for new front rotors, or do I need to with OEM? Thanks

I replaced mine with Gold Wing rotors. I have been using kevlar pads for about 40k miles, they stop better than OEM and no more ugly grooves. They polish the rotors to a nice shine.

I recall (but have no links) that the Goldwing rotors are thinner than valk (2mm?), but fit, and have the same longevity rating.

Mine are a bit cupped (but not grooved), but still working fine.

The Valk rotors are 4.5mm with a service limit of 4mm.  The 1800 wing rotors are 4mm with a service limit of 3.5mm. I had wing rotors on my previous Valk. Liked them better because they were lighter with cutouts in the center section.

Just curious, but with what mileage you guys had to replace the rotors?

I'm curious also. I'm at 145k. I guess I need to go purchase a micrometer.

I replaced mine at about 90k mostly because I couldn't stand the sight of them. Go with kevlar pads  and your rotors are still mint with 40k miles on them.

@Jruby38, Any downside to Kevlar pads? Is there a particular brand you'd recommend?

Well I'm only at 67,000.  For about the last 30,000 I've been running Honda OEM pads.  In addition to the type of pads you run, rotor wear (that is brake wear) will also depend on one's riding style, the Topography of the Terrain (lots of hills?), if it's a Dusty environment and things like that

Here is an old post about rotors I used,, they are working fine. You will need to do your own research to track them down. They were shipped Fed Ex air, I received them from China in two days.

want the best brake stopping performance, your life my depend on it only use oem or pad material Sintered Bronze HH friction which OEM are.  They have minimal warmup time meaning they will start griping almost immediately in cold and wet conditions, kevlar takes longer to grip.

Has anyone tried the EBC MD1014X or MS1014XC rotors? They look pretty good, and are lighter than OEM.

I'm running an EBC on my rear and until I put EBC pads on it it didn't work well at all. I guess that makes sense. But I think I'm not going to go with EBCs for my front rotors

I run the EBC VR1014BLK discs with their semi sintered pads and riding round the local twisty mountain roads locally they perform really well. Better feel and better stopping than OEM. I tried the organic pads in them and they were no where near as good. YMMV.
