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. The clamps are CNC machined from 6086 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. 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 use the OEM rubber cones, sold as a pair, 5mm Offset. Fits: All Kawasaki KX/KXF Dirt Bikes 2008-2013 with Replaceable Bar Mounts.
