BACKSTORY: A motorcycle swingarm (or swinging arm), originally known as a swing fork or pivoted fork, is a single or double sided mechanical device which attaches the rear wheel of a motorcycle to its body, allowing it to pivot vertically. The main component of the rear suspension of most modern motorbikes and ATVs, it holds the rear axle firmly, while pivoting to absorb bumps and suspension loads induced by the rider, acceleration, and braking.

Originally motorcycles had no rear suspension, as their frames were little more than stronger versions of the classic diamond frame of a bicycle. Many types of suspension were tried, including Indian‘s leaf spring suspended swingarm, and Matchless‘s cantilevered coiled-spring swingarm. Immediately before and after World War II, the plunger suspension, in which the axle moved up and down two vertical posts, became commonplace. In the latter, the movement in each direction was against coiled springs.

Some manufacturers, such as Greeves, used swingarm designs for the front forks, which were more robust than telescopic forks. In particular, sidecar motocross outfits frequently use swingarm front forks. The swingarm has also been used for the front suspension of scooters. In this case it aids in simplifying maintenance. In motorcycles with shaft drive, such as the Yamaha XJ650 Maxim, the shaft housing forms the left side swingarm.

Swingarms can be single or double sided, and have appeared in a variety of geometries. Many single-sided also incorporate the driveshaft.

Single-sided swingarms date from at least the late 1940s. In 1948, the Imme R100 produced by Norbert Riedel of Germany had both a single-sided front wheel suspension as well as a single-sided rear swingarm that doubled as the exhaust pipe.^[3] In 1950 Moto Guzzi introduced the Galletto, a large-wheel step-through scooter. In 1980, BMW introduced its first single-sided swingarm on the R80G/S, the “Mono-lever”, which was superseded by the “Para-lever” used currently. Honda currently features this style of swingarm on the Honda VFR. Ducati has created several models featuring single swingarms, most notably the Massimo Tamburini-designed 916 series. While Ducati abandoned this style for the 999, the company returned to it for the 1098 superbike in 2007, and it survives in the current Ducati 1199. The Triumph Sprint ST and Speed Triple also feature single-sided swingarms.^[4] (SOURCE: Wikipedia)
