Motorcycle saddles

Motorcycle saddles

The rigid suspension of the motorcycle's rear wheel was practically preserved until the second half of the 1930s (sprung rear wheel was found sporadically, e.g.. on ABC z 1919 years and the Indians 1000 Powerplus from the turn of the second and third decades - leaf spring, Danish Nimbus model 1923 - rocker arm on coil springs, Pullin i Groome z lat 1920/25 - swingarm with telescopic suspension, some Brough Superior - control arm with center spring and Bentley-Draper damper). Constructors' activities, to ensure proper driving comfort, they turned in a different direction. Their subject of research was the saddle.

The first saddles were similar to bicycle saddles. They were suspended in the rear part on two springs (compressed or stretched) shock-absorbing and had a leather cover. The next structures had a steel skeleton already formed, on which the springs were stretched, covered with a leather drawstring, riveted to the edges of the skeleton. The most typical of this type of saddles - known as Terry - was quite comfortable and stable. The leather top of the saddle was soon replaced with a rubber one - made of natural or synthetic rubber - and thanks to the shock-absorbing properties of the rubber, the number of springs stretched on the skeleton was reduced.

The result of further searches was the so-called. Swinging saddle, with a hardness proportional to the load and the magnitude of the shocks accompanying the ride.

Triumph has developed a saddle for touring bikes, whose flexibility could be adjusted by tensioning the springs according to the weight of the driver and the expected unevenness of the road surface. Other companies have also used similar designs, i.e.: BMW, Zundapp, Victoria etc..

German DKW produced the saddle, whose spring can be tensioned (with a large wing nut) while driving.

Finally comes the single and then the double sofa saddle, mounted on the top of the frame. The first attempts to find an original and at the same time comfortable seat deviating from the classic solutions are presented: Megola (1922), Ner-a-Car (1921), Neander (1929), AJS (1948) in inside. However, priority is given to Vincent HRD in this regard, which in the Rapid model 1000, already in 1938 of the year used the Feridax rubber double sofa saddle, shaped like a violin box. This design gained widespread recognition and application only after the Second World War.
