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.
[1] [4] The 2016 model had compression ratio of 13.2:1 and 2017 model has increased compression ratio to 13.6:1. [1] The 2017 model comes with Cruise control as standard and has upgraded electronics such as lean angle sensitive traction control , ride by wire , and optional track mode along with previous model's cornering ABS , quickshifter ...
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase , steering axis angle, fork offset, and trail.
Except for the engine change, the 1966 models of CT200 and CT90 were the same—the change in model number reflected a new Honda policy that model numbers would indicate engine-size class. The CT200 and 1966 CT90 had a dual rear sprocket, which created a lower gear range for heavy weight or steep terrain.
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.
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 must be increased by 7.28°: a nearly 30% increase.
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.
Typical gear ratios on bicycles range from very low or light gearing around 20 gear inches (1.6 metres per revolution), via medium gearing around 70 gear inches (5.6 m), to very high or heavy gearing around 125 gear inches (10 m). As in a car, low gearing is for going up hills and high gearing is for going fast.
