Independent left and right risers adapt to any handlebar clamp width. Anti-Vibe design reduces vibration in bars and helps reduce rider fatigue. Dual rotation points allow rider to select optimum riding position for comfort and control. Fit your machine's 7/8" bar clamps; allow you to clamp 7/8" or 1-1/8" taper bars. Engineered and tested for maximum strength and durability. CNC-machined from billet 6061-T6 aluminum with a black anodized finish. Made in the USA. Confirm you have sufficient clearance below Anti-Vibe bolt when turned full left or right; bolt extends below OE saddle clamp 7/8".. First determine if you have adequate brake line/cable length and stem clamp clearance before installing handlebar risers. Longer cables may be required when installing handlebar risers on some models..
