French Monet Goyon model RC4. This is a 350cc Villiers 2 tact with dual exhaust sport model. Motorcycle is partially restored and there are 2 extra engine blocks with it. Most missing parts are so new for sale at Chambrier in France. The heaviest 2 tact they built, this is a very fast motorcycle.

Nice base to build your own flattanker Beach Racer or to rebuild back completely original.
