MSS 500 O.H.V
The high performance overhead valve engines are developed from the well tried Viper and Venom engines. Set to give the maximum power with an open exhaust system, and with monobloc Amal carburetters, in appearance the machines are almost identical and they differ only in engine and carburetter sizes, compression ratios, and overall gear ratios. Crankcase protected by undershield. Velocette four-speed gearbox and with the special driving sprocket and 60 tooth rear chain wheel, provides low overall ratios for scramble work. Rear hub and brake drum has six-stud wheel mounting for extra loads. The front fork has two-way damping; sliders are protected from mud by rubber gaiters. Rear swinging arm of standard Velocette design with specially designed suspension units. Mudguards in polished aluminium with large tyre clearance; front arranged to prevent mud clogging the wheel.
