Details The Renthal Twinwall Handlebars are a design that is truly unique. With a construction that uses a 7010 T73 aluminum alloy inner bar to resist mechanical damage, and an outer bar of 7010 T6 aluminum alloy that resists extended wear, these bars are built to shrug off all sorts of damage. A cross brace adds even more support and includes Renthal’s specially developed bar pad to soften any painful impacts. Renthal offers several different contours of bar based on the riding ergonomics of the biggest names in the motocross like Villopoto, Windham, and Carmichael. Combine this with other features like a reinforced clamping area, a knurled clutch side bar end, and multiple seals that keep water out, and you have a set of bars that makes comfort a priority and fatigue failures a thing of the past.
