History
The Bitubo, marked by an exhaust system with a single valve and two divergent tubes, was the second stage of a project whose aim was standard production of an engine with intake valves and high performance, but meant specifically for road use.
Overall the vehicle was almost identical to the Tre Valvole (three valves), with some variations on the engine (only two inclined valves on the head; rocker arms, tappets and return springs within a wet sump in an aluminium box on the head), and maintained the flat, fish-tail exhaust.
