BMW Stock Wheel to GSX-R Fork Complete Conversion Kit - 55mm Offset

BMW Stock Wheel + GSX-R Fork Conversion Kit

This complete Cognito Moto conversion package combines our BMW stock front wheel to GSX-R fork adapter kit with a 55 mm offset triple tree kit. It is designed for builders who want to retain the original BMW front wheel while upgrading to modern 2006-present Suzuki GSX-R600, GSX-R750, or GSX-R1000 forks.

Select your BMW model group, the GSX-R fork year/model you are using, and your preferred triple clamp setup. We use those selections to supply the correct wheel adapter components, axle, rotor adapters, fork clamps, steering stem, and bearing setup.

55 mm Offset

All triple tree options in this package use a fixed 55 mm fork offset. This is the offset we use for this BMW/GSX-R conversion package.

• Custom steering stem for the selected BMW frame
• All Balls taper roller conversion bearings
• Adjustable steering stops
• BMW stock wheel to GSX-R fork adapter kit

Brake Rotor Requirements

This kit is designed to use GSX-R brake rotors that match the year and model of the selected GSX-R fork. GSX-R rotors and GSX-R rotor bolts are not included. The original BMW rotor bolts are reused to attach the Cognito Moto rotor adapters to the BMW wheel.

No modification to the BMW wheel or GSX-R forks is required.

Before Ordering

Please verify that the BMW model group and GSX-R fork year/model selected match the parts you are using. If your BMW or fork is not listed, contact us before ordering.
