MV Agusta 175 CSS Squalo, gear-driven camshaft
This bike has been developed for road racing based on the original 175 overhead cam single cylinder lay-out. Its closed cradle frame was almost identical to the grand prix 125 bi-albero racers. Ignition in this bike was by an external magneto at the left side of the engine. It was equipped with a five-speed gearbox, had a still wider finned engine head to allow for longer valve springs, and the CSS inter adjustable cam.
This bike is technically identical with the Squalo, the frame is a replica, the engine has four gears, not five, but the camshaft is driven by a train of gears fitting in the hollow space on the left side of the cylinder, where normally the chain drive is located. The chain drive of this engine has always been the weak point, and needed frequent maintenance and adjustment. This is overcome by this gear train which has excentric adjusters both at the bottom and the top end. The cam on this bike is of the inter-adjustable type. Only 113 Squalos were made. A modified and lightened front suspension, earless type, as on some of the grand prix racers, was used. The tank was designed for long distances and could hold 19 liters. This version was only available in 1954 and 1955. The engine was an up tuned form of the CSS lay-out, and the maximum rpm reached now 8.800. The cylinder head had much greater cooling fin area. Compression ratio was higher by means of a high dome piston.
