Good purchase. Gave me the right offset for the right price.
These seem to work OK, but the machine work is poor. I work in machining and am always impressed with how well most aftermarket parts are machined. These are the exception. Heavy machine marks and burrs. Because they are anodized they cant be fixed.
The 2014 & 2015 Yamahas have one flaw in my opinion - under steer where the bike wants stand up in the corners and needs to be pushed into the entry of the turn. Once in the turn the bike turns great.
These 20mm offset clamps (stock is 22mm) fix the under steer completely and the bike now loves to enter corners and stays in the groove allowing me to rail the outside of the corner. I also did not notice any noticeable change in headshake during high speeds which I expected. This clamp set-up gets my double thumbs up : )

You may look at like the Ride Engineering clamps as they have the stem for most all models.
