After receiving the M&P risers I can't recommend them what so ever, they have multiple issues and appear to be unfinished.
The risers I received looked like forged alloy, one was painted silver and the other was bare metal, both risers required modification to fit, I'd say they were meant to be machined down by 1mm on all surfaces before they were packaged but this clearly didn't happen as there was no way they were suitable for a 22mm bar so I was forced to work on them until they were a close enough fit for the job and finally painted them black.
I havent used the bike yet but if they ease my shoulder pain I'll definitely be buying a set of SW-Motech risers to replace these..
