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.
Motorcycle testing and measurement includes a range of more than two dozen statistics giving the specifications of the motorcycle, and the actual performance, expressed by such things as the output of the engine, and the top speed or acceleration of the motorcycle. Most parameters are uncontroversial and claims made by manufacturers are ...
It is a race-replica based on Suzuki's 250 cc (15 cu in) GP bikes from 1987 to 1998, the RGV V-2 racer. This motorcycle replaced the RG250 Gamma, which employed an alloy frame with a two-stroke parallel twin engine. The bike produced over 60 bhp in a narrow power band between 8,000 and 11,000 rpm. The dry weight ranged between 128 kg (282 lb ...
Developed in cooperation with Ducati Corse, the 848 trellis frame uses a simplified tube layout from the Ducati 749 with main section tubes that are enlarged in diameter from 28 mm to 34 mm, while being reduced in thickness from 2 mm to 1.5 mm. Ducati says this results in a 14% increase in rigidity and a weight savings of 1.5 kg (3.3 lb), helping the 848 weigh a claimed 20 kg (44 lb) less than ...
The steering ratio is the ratio between the theoretical turning radius based on ideal tire behavior and the actual turning radius. [9] Values less than one, where the front wheel side slip is greater than the rear wheel side slip, are described as under-steering ; equal to one as neutral steering; and greater than one as over-steering .
a 2006 Tete de Course, designed for road racing, with a head angle that varies from 71.25° to 74°, depending on frame size. Due to front fork suspension, modern mountain bikes —as opposed to road bikes —tend to have slacker head tube angles, generally around 70°, although they can be as low as 62° (depending on frame geometry setting).
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.
