BMW R / BMW K Series

BMW GSXR fork adaptor kit

If you’re looking to upgrade the suspension on either your R or K series BMW with the cast aluminium wheels, then this kit makes this a simple and easy upgrade companion. Allowing you to mount a set of modern brake rotors and modern stopping power whilst retaining that OEM look of the original BMW wheel.

This is designed to fit the 4 bolt pattern BMW wheels that came on the later R series and early K series bikes,  and comes with everything needed to mount it all up.

The smaller stainless steel spacer components of our kit are dual function, encapsulating the bearings giving added protection whilst also spacing the wheel correctly. Everything has been designed to work together and follow our design ethos of being simple and beautifully functional. These spacers also allow you to use the original bearings of the BMW wheel as they’re designed to insert into the inner diameter of the bearings and hold the GSXR axle in the correct alignment.

The kit requires the GSXR original axle and the L series forks, as there is no modifications needed to any existing BMW components. This really is a bolt on upgrade. If you are unsure of whether these will fit your GSXR forks or the BMW wheels you may have there are two measurements to check which ensure correct fitment. The GSXR forks need to have a measurement of 154mm between the flat surfaces of the axle position, and the distance between the rotor surfaces on the wheel should be 70mm (later cast aluminium wheels).
