4-Post Rubber Isolated Bar Mounts, Yamaha Cone Interface Our lightweight 4-post bar mounts eliminate twisting due to small crashes and tip-overs without sacrificing vibration absorbtion like a solid mount would. Four sets of bushings absorb hard hits and track roughness without compromising steering precision. Three different rubber bushing sets (soft, medium, and firm) are included to fine tune the feel. These bar mounts fit many Yamaha motorcycles using a rubber cone interface (most all 4-stroke off-road and motocross bikes), see the fitment tab below for specifics. They will work in both the forward and back triple clamp mount hole locations and have the same bar offset geometry as stock with only a 4 mm height increase. Handlebar size is available in both standard 1 1/8"
