Reiner builds first-class custom conversions of all kinds in the Thunderbike Custom workshop. Privately it may like to be a bobber of the old school with slight Ratbike influences. Thus, his early Evo Sportster has a rigid tail with fixed mounted custom fender. Only the swinging solo seat and the thick tires at the rear provide a minimum of suspension comfort. In front a classic Springer fork is used, which fits perfectly into the line. The conversion to chain with perforated sprocket brake, as well as the homemade manifold with our Tapered mufflers also fit perfectly into the concept.
