A motorcycle fork is the portion of a motorcycle that holds the front wheel and allows one to steer. For handling, the front fork is the most critical part of a motorcycle. The combination of rake and trail determines how stable the motorcycle is. The 'fork' on a motorcycle consists of multiple components.
The basic motorcycle swingarm is a quadrilateral, with one short side connected to the motorcycle's frame with bearings so that it can pivot. [14] The other short side is the rear axle around which the rear wheel turns. The long sides are connected to the motorcycle's frame or rear sub-frame with one or two shocks with coil-over springs.
One documented example of someone successfully riding a rear-wheel steering bicycle is that of L. H. Laiterman at Massachusetts Institute of Technology, on a specially designed recumbent bike. [28] The difficulty is that turning left, accomplished by turning the rear wheel to the right, initially moves the center of mass to the right, and vice ...
With one spring above the rear axle and two below, [3] [4] the sprung hub provided about two inches of vertical travel [1] [5] and weighed 17 pounds (7.7 kg) more than a conventional hub. It was designed to allow rear suspension to be offered optionally without altering Triumph's existing frames. [ 1 ]
Unsprung mass is a consideration in the design of a vehicle's suspension and the materials chosen for its components. Beam axle suspensions, in which wheels on opposite sides are connected as a rigid unit, generally have greater unsprung mass than independent suspension systems, in which the wheels are suspended and allowed to move separately.
Transverse linear motorcycle steering damper (centre foreground) The steering damper or steering stabiliser is a damping device designed to inhibit an undesirable, uncontrolled movement or oscillation of a vehicle steering mechanism, a phenomenon known in motorcycling as the death wobble. The stabilizer absorbs unwanted energy in the side to ...
Climb-Away transmission. Full suspension, 12-inch (300 mm) tractor tire on rear wheel. A 5.70-8 front tire was offered as an option. 760: Chain-drive. Similar to 750 except with 8" rear wheel. 770: Chain-drive. Briggs & Stratton engine. Climb-Away transmission, 12" rear wheel, one-piece foam seat; only model that did not have a back fender.
The Steffey motorcycle in 1902, essentially a bicycle with a two-stroke engine attached, used wooden, rims with wire spokes. [1] This style of wheel evolved into a stouter motorcycle-specific wheel, still with spokes, up to the 1960s and beyond. [2]: 134 In April, 1922, Borrani started production of motorcycle wheels with an aluminium rim. [3]
