Matchless Silver Hawk
Matchless Silver Hawk
.
What a fascinating display must have met the eyes of thevisitor to the Olympia Motor Cycle Show in November 1930. Virtually everymanufacturer had something new and exciting (New Hudson, for example, hadcompletely revamped their range from head to toe), and there was not just onetotally new British four-cylinder to be seen, but two! We met one of the new'fours' earlier in this book, in the shape of the Ariel Square Four. Now meetits rival, the Matchless Silver Hawk which was, or so the makers claimed intheir sales literature, 'unquestionably the most fascinating machine to ridethat has ever been built. It combines the silence, smoothness and comfort of themost expensive motor car with a super-sports performance. On top gear alone themachine will run from as low as 6 miles per hour to over 80 miles per hour,while the acceleration given by the four-cylinder overhead camshaft engine inconjunction with the four-speed gearbox must be experienced to be believed.'
That says it all, really. But for all its proclaimedvirtues, the Matchless Four did not exactly take the world by storm, and afterstruggling on for a few seasons, it was quietly dropped from the range in 1935.No discredit to the bike itself, of course, but these were the Hungry 'Thirties,the years of the Great Depression and the money was scarce. There was possiblyenough of a market to support one luxury four-cylinder model, but not two. In ahead-on battle for sales, the Ariel Square Four won, and the rival MatchlessSilver Hawk lost out.
Still, the Hawk was quite an imaginative design, and forall its resemblance to the Square Four it was actually a narrow-angle vee-fourmuch in common with the same factory's Silver Arrow monobloc twin of theprevious year. There was just one crankshaft set across the frame and,unusually, it had a centre bearing mounted in a plate - a feature that would berepeated a couple of decades later in the AJS and Matchless vertical twins.
A single overhead camshaft ran across the cylinder head,driven at the right-hand side by a substantial shaft and bevel-gear arrangement.Ignition was by dynamo and coil, the dynamo being driven by skew gearing fromthe camshaft-drive vertical shaft. The oiling system was dry-sump, with the oilcarried in a pressed-steel tank at the base of the front-down tube, bolteddirectly to the engine's crankcase.
The frame was the one which also housed the smaller vee-twin,and featured cantilever rear springing in which the rear sub-frame pivoted inSilentbloc rubber-bonded bushes behind the gearbox. Two compression springs weremounted under the saddle, and damping was by friction discs, controlled by aknob. Brakes were coupled 8 in. diameter, meaning that both front and rear drumscame into operation if the brake pedal was pressed, but the handlebar leveroperated the front brake alone.
In the years ahead, Matchless carried out very littledevelopment on the Silver Hawk, except that in its final period a footgearchange was available to option at £1 10s extra, and it seemed almost asthough they themselves had little faith in it. Perhaps they hadn't: when'Torrens' of the Motor Cycle (editor Arthur B. Bourne) wanted to buy a newSilver Hawk in 1935, the makers advised him to go and buy an Ariel instead.Which he did....
