It all started in the last years of 50cc GP racing by Kreidler. Herbert Rittberger made an engine for Kreidler under the name of Rimotu (Rittberger Motoren Tuning). In the 80cc it raced as Zündapp and Krauser, with Bakker or LCR (Louis Christen Racing) frames. The factory racers were Hubert Abold and Stefan Dörflinger, in the Netherlands Bert Smit raced an LCR Krauser with sponsorship of John Bestebreurtje. In 1988 he won the European Championship race on Thursday and became third in the TT race at Assen on Saturday!!
