All parts of the bike are glass bead blasted in advance, then powder-coated with high-quality paint. The tank is painted in a matching vintage style. The tank lining is handmade!

Engine & Drive

The motor is completely revised and renewed except for the last screw or seal. The same applies to the manual transmission and the final drive. All or nothing!

Attachments & Accessories

Our customers trust in quality - that's exactly what we do. All attachments and accessories are made by renowned manufacturers such as Kellermann or Motogadget.


The frame is adapted to the Bobber look. This means: CNC-milled and turned seat tube, water-cut suspension mounts and shortened fork.


As the only company in Switzerland, we have the approval of our self-built exhaust system in combination with open sports air filters.
