Engineered for serious four-stroke performance, the FMF Racing PowerBomb 040021 header utilises FMF’s patented PowerBomb technology to dramatically boost exhaust flow and enhance throttle response. The strategically located PowerBomb chamber increases exhaust velocity, ramps up power, and reduces sound output by allowing exhaust gases to expand and cool before rapidly accelerating through the system. Crafted from tough stainless steel, the PowerBomb header is ideal for aggressive riders seeking both increased midrange and high-end gains from their Honda XR650R. Suitable for closed course competition only.
