new brake rotors

[Yamahahammer1300]

I have felt a pulse for a while, finally checked the runout of my front rotors.  Not good.  I recently replaced the front wheel bearings, used gold dot calipers and hoses.  What is a good upgrade for rotors?

RPM offers 5 different brake rotor options.

If you are on a tight budget many have gone with the Chinese made Arashi wave rotors, including myself.

Mine is 89.  Do these rotors work through 90 and 89?

'89 and up all have the same rotor size.

Thnx, Mark.

Go with the Arashi's. I had a set of S3 rotors fitted that are identical in appearance to Arashi rotors but are more expensive in price. They were on the bike for about four years before eventually warping to the stage  where they had to be replaced. Got a set of Arashi's fitted now and so far after two years have no complaints with them, the quality is on par or better than the S3's.

I have 23K miles on my Arashi rotors with zero issues. Time to check the fork oil...

I have been 100% satisfied with the Arashi rotors.



This was after a crash stop from well north of 200 kph. They are regularly used to the point of the rear wheel chattering and at least a couple of times every ride I do a max rate stop from highway speeds just to keep the "feel" fresh.

They are used hard and with nearly 100,000 km on them still not a hint of runout and the paint on the spiders not so much as a chip.

What else do they need to do?

^^^This is so important ^^^.

All the fancy brake/wheel/tire components mean absolutely nothing if you don't regularly practice using their full potential.

Practice, practice, then practice some more...

Thanks Noel!

Hmmm, well practice is important... yet the comment "...brakes are regularly used to the point of the rear wheel chattering..." is as inane as it is dangerous.  That subject, in the form of a question, was referenced several years ago however I am unsure if it was answered so it is addressed now...

If, when under hard high speed braking (especially at an impressive "well north of 200kph"!) the rear wheel is chattering, for safety's sake what should the rider be doing – think slipper clutch – yep, feather the clutch and it will help to eliminate or at least minimize the rear wheel chatter which you are experiencing... so practice in a more constructive manner would seem beneficial.

At speeds considerably less than 200kph rear wheel chatter can be problematic...

In fact rear wheel hop is as problematic as the discolored discs you pictured – true, there is a lot of heat being generated as the discoloration indicates – however absolute stopping power is achieved not by high discoloration – however brake fade is a result of excessively high disc temperature.
 
Unknown are what brake pads you are using, yet perhaps changing to a set better matched to the discs would result in less discoloration... not to mention better braking performance.

Just a thought you might ponder – especially when meandering "well north of 200kph"...

Smile gentlemen, it's all in good fun so ride (and stop!) safe.
