The TWN (Triumph-Werke Nurnberg) Coronet has just arrived and is on display with the other 100 plus bikes in the collection at our Grassmere store.
This bike is a little different, not only is it a German made Triumph but it also has a split single engine! The 'Twingle' sends the intake fuel-air mixture up one bore to the combustion chamber, sweeping the exhaust gases down the other bore and out of the exposed exhaust port.
