Some of the applications can be upgraded, but others cannot be upgraded.

MTC will sell the parts to the do it yourselfers or will perform the upgrade for a nominal fee, plus the cost of parts.

The KZ, J-model, GPZ, ZX-11, Suzuki GS, and Hayabusa can all be upgraded to the larger studs, but the GSXR 1000/1100 and ZX-12 cannot. The reason for this is the lack of clearance inside the inner hub for the larger studs and locknuts.

Please contact us for information on what parts you'll need to send for the upgrade.
