For this BMW GS1150 a special kit has been developed in cooperation with BMW-dealer Bert Duursma from Apeldoorn. This kit allows you to take your BMW Off Road. The kit consists of a specially designed frontframe which replaces the entire original system, a long 'Off Road' WP front fork, an aluminium rearframe and a WP rear shock-absorber. You can also choose between the original spoke and the optional special spoke wheels.
