BMW R100 exhaust system with DTC report Switzerland

The flying spark

BMW R100 - 1981 - October 2020

On the squares, ignition lock on and off!
Our last conversion is based on a BMW R100 RT from 1981 – completely rebuilt, 100% restored and a real eye-catcher. The 100% road-approved motorcycle in Switzerland convinces with its very special paintwork, a new exhaust system and many small details that make the heart of every lover beat faster.
A heartfelt thank you to our excellent photographer, phPics Photography.
