The Harley-Davidson Motor Company, of Milwaukee, Wis., in contrast with its complete line of 1923 models, shows a 1913 Harley-Davidson twin as sold ten seasons ago. Comparing the present non-electrically equipped model with that of 1913 demonstrates the great advances in engineering and design in the decade just passed, and also that while present prices are not higher, the value to the rider has been increased for the same outlay. Not only is this obvious to the eye, but a study of the standard construction of 1923 will show this even more noticeably. Take the brake, for example. The lining for the 1923 model is much wider and thicker; more of the lining surface is in action (all as compared with about 60 per cent in 1913); the pedal control is more sturdy and easier to operate. The present valves are of Silchrome steel as compared with the plain steel valves of 1913. The increase in comfort through the use of the auxiliary buffer springs, the air-cushion saddle and the firm’s spring seat post is likewise obvious, for on the 1913 model (which was, as veteran riders know well, by no means uncomfortable) the spring seat device and Sager type front fork only were fitted.
