7075 Aluminum tubing is formed, then shot peened and heat treated for strength. The FMF 909 is constructed with a strong 5mm wall thickness where it's needed most. Crossbar and clamps are extruded and machined for percise fit. The crossbar pad is included with all bars. Laser etched positioning guides and 909 logo will give your bike a high quality look. Knurling on clutch side helps prevent grip slipage.
