Description
Motorcycle restored in show condition. Ready to drive. Ask me for a video of the motorcycle driving and I will send it to you by WhatsAppThe silver Hawk owns more than a little to the same company’s innovative 400 cc Silver Arrow narrow angle V-twin of a year earlier.
The engine arrangement is equivalent to two Silver Arrow engines set side by side, but whereas the twin has side valves and a leisurely manner of going, this new four boasts bevel drive to an overhead camshaft and all the performance that most riders of the day can handle. Positioned with its crankshaft across the frame, the engine is particularly neat, all four cylinders being cast in one unit, the crankcase compact and sturdy.
The primary drive utilizes a duplex roller chain and runs in an oil tight light alloy casing, the chain being tensioned automatically by spring steel blades on both top and bottom runs. This system is produced under Weller patents.
A Lucas dynamo-coil-distributer mounted above the 4 speed Sturmey Archer gearbox attends to sparks, lights and battery charge.
The machine has a “Matchless “ patent spring frame with cantilever rear suspension and instantly adjustable shock absorbers which can be adjusted while the machine is in motion.
The company claims a power output of approximately 26 B. H. P.
