A motorcycle transmission is a transmission created specifically for motorcycle applications. They may also be found in use on other light vehicles such as motor tricycles and quadbikes , go-karts , offroad buggies, auto rickshaws , mowers, and other utility vehicles, microcars , and even some superlight racing cars.
A hub gear, [1] internal-gear hub, [2] internally geared hub [3] or just gear hub [4] is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed ...
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of ...
In developing countries where typical motorcycles are 125–150 cc (7.6–9.2 cu in) displacement, the larger 249.5 cc (15.23 cu in) CBR250R is at the higher end of the sport bike range, [10] looking similar to much more powerful sporting machines with its full fairing in Honda's new layered style that was introduced on the 2008 CBR1000RR Fireblade and 2010 VFR1200F.
A single-speed bicycle is a type of bicycle with a single gear ratio and a freewheel mechanism. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle. Adult single-speed bicycles typically have a gear ratio of between 55 and 75 gear inches, depending on the rider and the anticipated ...
The result is the ability to sweep the transmission through the entire ratio range smoothly, while in motion, under load, or stopped. Two factors allow the NuVinci CVT to provide a continuously variable ratio range in a compact package: The first is the geometric configuration of the drive, which is based on differing contact ratio of a sphere.
