Twin Motorcycles Developed a complete stock look a like new called HPA = High performance airbox for the XR1200 and XR1200X models from 2008 and up.
The development of this High Performance airbox for the XR1200-XR1200X can be seen here. The material is Polyurethaan, this material is almost the same as the original material SO NO CARBON FIBER. We kept the stock design and improved the clearance for legs. The stock XR1200X airbox comes a little out of the gastank, Our is nicly tucked in the gastank just a little.
