Renthal 7/8" handlebars re-wrote history when they became the first aftermarket aluminum handlebar to be fitted as O.E.M. on a Japanese motocross motorcycle. All Honda CR/CRF and Kawasaki KX/KXF models (except minis) are fitted with a Renthal 7/8" handlebar as original equipment. The exclusive aluminum alloy and the advanced manufacturing processes Renthal uses result in a handlebar which is more than capable of withstanding the extreme rigors of motocross and supercross riding and racing. The following features are integral to the Renthal 7/8" handlebars: 7/8" (22 mm) external diameter to fit most standard-sized clamps and controls. 7010 T6 aluminum - which Renthal has exclusive rights to - is a specially developed alloy for the manufacture of handlebars. High impact strength, lightweight and excellent vibration dampening. Shot peened surface finish to help prevent fatigue failure. Knurling - grip end only - increases bonding between bar and grip. No knurling in clamp area, this could cause stress on the riser and lead to fatigue failure. Anodizing - a 15 step anodizing process forms an integral coating giving protection against corrosion. Renthals copyrighted, bonded lightweight single bolt clamping system for the cross-brace* greatly increases strength whilst still allowing flex. Laser-etched positioning grid. The highest quality - 35 individual steps / processes required in the production of each bar and 58 separate quality checks made. A specially developed injection-molded crossbar pad is included with every handlebar. * Note: The cross-brace is fitted to all Renthal 7/8" MX handlebars and the streetfighter handlebars. Renthal.
