Renthal's 1 1/8" (28.6mm) handlebar mounts are designed to allow the mounting of oversized 1 1/8" handlebars, such as the Twinwall or Fatbar, on certain model motorcycles which are equipped with 7/8" handlebars as standard. These are CNC machined from 6082 T-6 billet aluminum and black anodized with laser etched Renthal logo. The mounting studs are a special CNC machined hardened nickel chromoly steel with a machined relief to allow for the bending of the stud in the event of a hard crash. Our 1 1/8" mounts are meant to be a direct OEM replacement for the stock 7/8" mounts and will replicate the OEM bar position and height. Designed to allow the mounting of oversize 1-1/8" handlebars. CNC-machined from 6086-T6 aluminum and studs from hardened nickel chromoly steel. Utilizes the OEM rubber cones; not included.
