Denis Parkinson was Excelsior's factory racer. In 1936 he was the winner of the Manx Grand Prix TT on Isle of Man with this model. Denis Parkinson had 3 of these motorcycles at his disposal. This is one of these 3 motorcycles. It is not known if this is the training bike or the one he won with. What is certain is that this is probably the last one left. Everything about this bike is different from the normal road version. Motorcycle starts well and is very fast.Motornumer BR BR100
