I installed a 21in Reinforcer rim last weekend after putting a few hundred miles on my ABS light continues to come on as soon as I get bike to speed. I went with a Dunlop 130/60/21 thinking I wouldn't have any ABS issues. My rear is stock with a Michelin 180/65/16 has anyone else had this issue with this combination? I've read most if not all the threads that come up in search and it seems this combination should work. I've verified the wheel rotating in the correct direction and that the bearing was installed correctly etc.
Thanks

 

You're not supposed to have any issues with the 2014-later bikes when using the 130/60-21 Tire ... but it seems some still do

It seems the cheapest "Fix" is to use the Special ABS wheel bearing for those applications

Arlen Ness is one source for those bearings

Sounds to me like you need a diameter specific wheel bearing. Same thing happened to me when l installed a 21" front wheel. Ness has the correct bearing and it solved my issue.

Did you reuse the bearing from a 19 inch wheel?

 

No I used new bearings that came with the rim

 

I saw those bearings. I will call ness on Monday unless you know do I just need a front bearing now or do I need to change both front and rear?

 

I bought the 21" reinforcer and had the exact issue as you. My installer put the Ness bearing in that multihdrdr spoke of and now my light stays off as it's supposed to.Sport chrome wasn't very helpful they said the bearing they sent shouldn't throw a light but it did.

 

I'm willing to bet that it's just the front that you'll need.
