Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or "reverse trike" sometimes with front drive but ...
A tilting three-wheeler, tilting trike, leaning trike, or even just tilter, is a three-wheeled vehicle and usually a narrow-track vehicle whose body and or wheels tilt in the direction of a turn. [1]
The increase in lean angle due to a tire thickness of 2t can be calculated as ( ()) where φ is the ideal lean angle, and h is the height of the center of mass. [9] For example, a motorcycle with a 12 inch wide rear tire will have t = 6 inches. If the combined bike and rider center of mass is at a height of 26 inches, then a 25° lean ...
Motorcycles with sidecars often have three wheels, but there has been some use of two sidecars (one on each side of a motorcycle, not a sidecar that seats two which is another thing). [38] In one case the use of flexible type sidecars allow the center-line motor bicycle wheels to stay on the ground, and providing adequate handling [ 38 ]
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]
As the early motorcycle industry progressed, larger tyre sizes accompanied larger engine displacements, so that by 1909–1914, 2 + 1 ⁄ 4 in (57 mm) section, 26 in (660 mm) diameter tyres were used on 250 to 350 cc (15 to 21 cu in) motorcycles, and 2 + 3 ⁄ 8 to 2 + 1 ⁄ 2 in (60 to 64 mm) section tyres appeared on motorcycles with ...
Yamaha entered the ATC market in 1980, after paying patent-right to Honda to produce their own version of the All Terrain Cycle. Starting modestly with a 125cc recreational ATC that would remain the foundation of their line through 1985, the YT125 featured a 2 stoke engine with sealed airbox with snorkel intake, an autolube oil injection system, and featured a narrow tunnel above the engine ...
Such tires are useful for enduro and dual-sport motorcycles and other vehicles designed to be used both off-road and on pavement. Some off-road tires are designed to be used with low inflation pressure on difficult terrain, reducing their rigidity and allowing the tread to better conform to the terrain. [3]
