Wheel flop refers to steering behavior in which a bicycle or motorcycle tends to turn more than expected due to the front wheel "flopping" over when the handlebars are rotated. Wheel flop is caused by the lowering of the front end of a bicycle or motorcycle as the handlebars are rotated away from the "straight ahead" position.
For a sample motorcycle moving at 22 m/s (50 mph) that has a front wheel with a moment of inertia of 0.6 kg·m 2, turning the front wheel one degree in half a second generates a roll moment of 3.5 N·m. In comparison, the lateral force on the front tire as it tracks out from under the motorcycle reaches a maximum of 50 N.
In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).
The most extreme example of this is where the wheel stops rotating altogether (wheel slide) while the train is still moving and can result in a “wheel flat” caused by the softer steel wheel being worn away by the harder steel rail. However, the wheelset does not need to lock up completely in order for damage to be caused.
The Vyrus 985 C3, an exclusive Italian motorcycle with hub-center steering, of which 24 were sold between 2004-2008 Hub-center steering in Bimota Tesi 1/D. Hub-center steering (HCS) is one of several different types of front-end suspension/steering mechanisms used in motorcycles and cargo bicycles. Hub-center steering is characterized by the ...
When a back torque comes from the transmission, the splined hub slides up the bearing ramps, disconnecting from the clutch plates and allowing a limited slip between input and output. This type of clutch is designed to partially disengage or "slip" when the rear wheel tries to drive the engine faster than it would run under its own power.
At a marathon the planners have a course maximum of 26 miles; a motorcycle ride would cover that while just getting warmed up. For most rides, a group ride organizer isn’t going to be applying ...
On bicycles and motorcycles, camber thrust contributes to the centripetal force necessary to cause the vehicle to deviate from a straight path, along with cornering force due to the slip angle, can be the largest contributor, [1] and in some cases is the sole contributor. [2]
