have a mint 52mm convertibar set for sale. had them on my 636 and they were great. I used some sheet metal as a spacer so they would work on my 50mm forks and i never had a problem with them. these are the older style bars too btw. $180 obo. let me know what they are worth to you ha.

 

Damn I need 50mm!!! Can you get 50mm for $180?)
