HIGH TECH FOR YOUR CLASSIC! This aluminium box swinging arm is the highest quality product from K&J. The latest technology was used to provide your bike with maximum riding stability. The chain tension on both sides is also kit in a twist-proof manner by the pin-locked excenter. It is made from drawn aircraft aluminium and has excellent rigidity due to the box profile. Thanks to high-precision needle bearings, a backlash-free mounting is guaranteed. The polished surface underlines the perfect finish. It is possible to fit a wider rim or a wider tyre up to a maximum of 180mm. The swinging arm is delivered ready for installation, incl. rear wheel axle, spacers and TÜV certificate. The original torque link and chain guard can no longer be used. Please order these parts (order no. 32-0965 and 32-0953) separately.
