If you want to improve your chassis, you need a better swinging arm! The K&J box swinging arm does not look showy and has a very good price/performance ratio. It is made of high-quality steel, has considerably better rigidity due to the box profile and very good bearing support thanks to adjustable tapered roller bearings. The chrome-plated surface is a great eye-catcher and offers excellent corrosion protection. It is also possible to fit a wider rim or tyre. The swinging arm is delivered ready for installation, including rear wheel axle and TÜV certificate. Stock torque link and stock chain guard can still be used.
