Big Force


customized Thunderbike Harley-Davidson FXDR

Here comes number 6

The GT is one of our sportiest custom conversions and features upside-down forks, big wheels and single-sided swingarm. 

As with the GT 3, the original FXDR tank has been replaced by a GP tank. The significantly slimmer and longer tank gives the bike a sportier line. This line is supported by our GP rear fender, which picks up the design of the tank and at the same time strongly highlights the 21″ rear wheel due to its reduced size.

In the front we install a triple clamp with rake, which allows us to install the large front wheel without losing too much suspension travel. To ensure that the larger wheels can also be braked well if necessary, the brake discs also grow in proportion to the wheel diameter. The GT uses 340mm discs, compared to the 300mm diameter of the standard model. This is made possible by specially developed caliper adapters that are mounted between the fork and the caliper. The paint design bears the signature of Chikos Pinstriping.
