britaxcooper Posted July 12, 2009 Share Posted July 12, 2009 Could someone tell me what this rear brake is out of? I was thinking XS500 or Ive seen similar on an RT3? Its 180mm and obviously the lightening holes are not standard. Link to comment Share on other sites More sharing options...

britaxcooper Posted July 12, 2009 Author Share Posted July 12, 2009 Thanks drewpy, I couldnt have asked for a better reply! It was in the rear of a Bultaco that I'm putting together for road racing, its against the rules to use jap parts so now I know what is it.

(wheel) but u should get away with puting it in a bulto ...... but tbh the holes look well naf and serve no perpose ! Regards Jim Link to comment Share on other sites More sharing options...
