Just curious....

 

My front be a 1000RR.

 

assume you're running some USD forks?

 

Yeah, forks, rims, calipers and fender are from a 1000. Someday I'll get around to putting that stuff in my sig.

 

I'm running CBR 1000RR front 600RR rear, the reason being that the 600RR uses the same width 5.5" as stock...

They are considerably lighter than the stock rims, but needs a 25 mm axle so it won't work on stock fork/swingarm...

 

I have a CBR1000RR front wheel, but it is to go with my USD forks. I don't think it'd work on the stock forks.

 

Perhaps a bearing change (to a smaller 20 mm ID) would work though....

 

Could be a possible solution yes... The bearings outer dimensions are pretty standard, so it should be easy to find a matching one...

But I still maintain that my method for fitting them, albeit more complicated is better...
