The 1914 Rudge lineup was announced in the October 30th, 1913 edition of "The Motor Cycle". Not that the features announced were etched in stone. As the year went by, the specification of the machines changed slightly.
Other features of 1914 models were the large silencer, usually fitted with a tail pipe, and smaller wheel rims to take 650 x 65 mm tyres. These wheels are easily recognised at the rear, as for both the Multi and the single speeder, the belt pulley was now the full diameter of the wheel rim. These belt rims (or "half rims" for the Multi) are pressed into the wheel rim and the two dimpled together. Only the T.T. Multi and the Brooklands Racer were fitted with a smaller rear pulley, spoked to the wheel rim.
One model not often discussed is the three-speed, fitted with a Sturmey-Archer rear hub gear. Just how many of these were sold I'm not sure. I have never seen one, nor bits of one, and don't even recall seeing a period picture of one. Surely they must have been made in small numbers, presumably catering for Multi gear skeptics.
Note the Bowden cable attached from the foot pedal on the right to the oil pump in the tank.
There were other improvements as well, such as the fitting of grease cups to the front fork shackles, but pretty much the models were simply undergoing refinement. Fairly radical - and lasting - changes came to the frame design as a result of Pullin's 1914 T.T. win, so that when production recommenced after the war, only the 750 cc machine retained the "high" frame.
