Like with the 125 cc, the cylinders are inclined at 35 degrees and are cast in one piece with the top part of the horizontally split crankcases, which are cast in light alloy, as are the cylinder heads (cast in one piece for the four cylinders). The various covers are cast in electron, an alloy of aluminum and magnesium. | ||
The double overhead camshafts are now driven from the center of the crankshaft by a gear train between the cylinders. To reduce the width of the engine, this gear train is partially situated behind the cylinders, and from there drives the magneto for the ignition. The valve angle is 76 degrees: 36 degrees for the inlet and 40 degrees for the exhaust valves. Bore and stroke are still 44 and 41 mm. Carburetion is by four Keihins with remote float chambers, with a rather steep downdraft angle for the inlet | The double overhead camshafts are now driven from the center of the crankshaft by a gear train between the cylinders.
