This wheel conversion kit from Cognito Moto allows you to install an original BMW Airhead front wheel onto modern BMW R nineT (R9T) forks (2014–present).
The kit includes rotor adapters, a new axle, and axle spacers specifically designed to adapt BMW wheels to fit R9T forks. It enables upgrading the front suspension of vintage BMW R65, R75, R100, K75, and K100 motorcycles using components from these newer forks.
To complete the installation, R9T rotors and rotor bolts matched to your fork model year are required (not included). No modifications to the R9T fork or BMW wheel are necessary. The BMW rotor bolts are reused to mount the adapters to the stock BMW wheel.
This fork and wheel swap is an easy bolt-on upgrade, maintaining proper geometry while retaining the classic BMW front wheel. It provides significantly improved handling and braking performance thanks to the modern R9T inverted fork design.
The procedure involves removing the BMW front end, installing the wheel adapters, new axle, rotor, and brake components before completing the fork installation. Check out our installation video for the full DIY tutorial.
Though this kit is designed for R75, R100, K75, and K100 BMW models, it may fit other Airhead bikes. Contact us if you do not see your specific BMW motorcycle listed. Take your vintage ride to the next level with this simple front end conversion!
We do not offer this for the R65 models wheels they are slight thinner we recommend swapping the wheel from a R75 or R100.
