The long way from the base bike to a Black Diamond.

BMW R80 & R100 Bobber

The BMW R80/R100 models, produced in the 1970s, tell a story that is more than 40 years old – we are continuing this with a new chapter. In our small but fine factory near to Solothurn, the motorcycles are completely dismantled, restored and rebuilt. We consciously do without mass production and transform every basic bike (BMW R80 / BMW R100) into an absolute unique piece. Whether on the engine or on the frame, we replace every screw and replace every seal – All-in-One! YOU decide what your motorcycle should look like from us!

Painting

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!
