Mounted on a standard Monolever BMW, the shock absorber is mounted behind a frame tube of the rear subframe. This is why the shocks have a short spring, mounted on the bottom part of the shock.
If your build is a caferacer with rear subframe, you can only mount the shocks with the standard configuration.
If you are building a Bobber configuration, then you can also choose your shock in the Bobber build category; we can offer shocks with reservoirs and shocks with a longer spring, mounted higher on the shock, this looks much nicer!!
The standard shocks also fit the Bobber of course.
