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 rear wheels of drift trikes are commonly made from PVC, or by sliding PVC or a polyethylene pipe over deflated pneumatic wheels and re-inflating them to lock them in place. Drift trikes also feature a solid, fixed beam, 'go-kart' style rear axle, which forces both rear wheels to spin at the same rate. The short wheelbase, or distance ...
Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or "reverse trike" sometimes with front drive but usually with rear drive. A variant on the 'one at the front' layout was the Scott Sociable , which resembled a four-wheeler with a front wheel missing.
The Servi-Car used variations of Harley-Davidson's 45 cubic inch flathead. From 1932 to 36, the Servi-Car used the engine from the solo R model. [1] It was changed in 1937 to the engine used in the W model, which differed mainly in having a recirculating oil system instead of the constant-loss system of the R. [2] [7] The "W" flathead engine continued until the end of production in 1973 ...
Steering requires that the axle(s) of the front wheel(s) form a finite angle with the axle(s) of the rear wheel(s), i.e. not be parallel. This misalignment may be accomplished in a variety of ways, and usually the front wheel(s) rotate about a steering axis relative to the rest of the vehicle and the rear wheel(s).
There are three typical configurations: motorized bicycle with sidecar; two wheels in the rear, one in the front (aka trike); and two in front, one in the rear (aka reverse trike). However, language and definitions vary.
The weight of a delta trike can be quite close to the weight of a tadpole trike if they are both of a similar quality and similar materials are used. The Hase Kettwiesel Allround delta trike has an aluminium frame and weighs 39.4 lbs (17.9 kg). [17] The Catrike Road tadpole trike has an aluminium frame and weighs 37.5 lbs (17 kg). [18]
A motorcycle (motorbike, bike, or, if three-wheeled, a trike) is a two or three-wheeled motor vehicle steered by a handlebar from a saddle-style seat. [ 1 ] [ 2 ] [ 3 ] Motorcycle designs vary greatly to suit a range of different purposes: long-distance travel, commuting , cruising , sport (including racing ), and off-road riding.
