The heart of the bike is an 844cc engine which, breathing through twin 36 mm carburetors produces a very healthy 81hp at 7600 rpm. That figure is impressive enough, but it doesn't really convey exactly what the engine is like. The engine and transmission sit in a large duplex frame with the sump hanging down between the bottom tubes giving the bike a low centre of gravity. The patented integral braking system has many advantages. Stopping in a shorter distances without fear of unbalancing the motorcycles.
