The original riding position of the passenger is not universally comfortable for most, due to the relatively high position of the foot pegs (to make room for the side cases). Fitting the Wunderlich lowering set will move the footrest 20 mm (~0.8")down and slightly forward. This change in footrest position will increase the knee and hip angle, a benefit especially when touring. Better blood circulation and fewer cramps will make long riding stints much more enjoyable. The original footpegs are retained, the original side cases can be used and no modifications to bike are needed at all. The kit consists of a left and right side adapter. Made of precision machined high quality aluminum alloy. Sold with all components needed for an easy installation.
