Thunderbike GP Wheel

Thunderbike GP Wheel

We have developed the GP wheel design for the Thunderbike GP Series. The custom bike, milled from a monoblock, is currently produced exclusively in the sizes 3.75×26 (front) and 9.0×21 for single-arm rear swingarms. It is produced in two different shapes, one for Harley-Davidson Touring models from 09 and one for Softail Rocker, Breakout and Thunderbike Custom Frames.

Suitable tyres are also available in our Online-Shop. With almost all wheel modifications it is necessary to install other mudguards, rear fenders or front fenders. The suspension travel and the vehicle height have to be considered. The rear wheel is only suitable for 08-17 Twin-cam models Rocker and Breakout with the single arm swingarm RS 21. For your Softail Breakout and Fatboy from 18 developed an extra light CNC milled aluminium single side swingarm kit. Here you will find the necessary Unbreakeble fork to mount the front wheel.  So that the Wheel can be adapted to your vehicle, an order in the online shop is not possible without further consultation. Please contact us by mail or phone!
