About us

The Diamond Manufacture

High-quality diamonds from the Mittelland, made in the beautiful Feldbrunnen, Canton of Solothurn – is there that? YES, it is! In our small but fine bike factory, we have specialized in the conversion of the so-called “cows” and “bricks”, i.e. the BMW K- and R-series. We restore, repair and refine the old motorcycles and turn them into a real diamond.

We love what we do.

More than just a workshop

Diamonds from the Midlands

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, the motorcycles are completely dismantled, restored and rebuilt. In our small but fine factory, 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. YOU decide what your motorcycle should look like from us!
