Motorcycle engine
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used in small numbers. Although some mopeds, such as the VéloSoleX, had friction drive to the front tire, a motorcycle engine normlally drives the rear wheel, power being sent to the driven wheel by belt, chain or shaft. Most engines have a gearbox with up to six ratios. Reverse gear is occasionally found on heavy tourers, for example the Honda GL1600, and sidecar motorcycles, such as the Ural.
Motorcycle
A motorcycle often called a bike, motorbike, or cycle is a two- or three-wheeled motor vehicle. Motorcycle design varies greatly to suit a range of different purposes: long distance travel, commuting, cruising, sport including racing, and off-road riding. Motorcycling is riding a motorcycle and related social activity such as joining a motorcycle club and attending motorcycle rallies. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle, and the first to be called a motorcycle. In 2014, the three top motorcycle producers globally by volume were Honda, Yamaha (both from Japan), and Hero MotoCorp (India).
2009 Isle of Man TT
The 2009 Isle of Man TT Festival was held between Saturday 30 May and Friday 12 June on the Mountain Course. The 2009 TT races again include a second 600 cc Supersport Junior TT race and the Lightweight TT and Ultra-Lightweight TT races held on the Billown Circuit in the Isle of Man. A new event for the 2009 Isle of Man TT races was the one-lap TTXGP for racing motorcycles "to be powered without the use of carbon based fuels and have zero toxic/noxious emissions." The Blue Riband event of TT Race week was won by Steve Plater claiming victory in the Senior TT and also winning the prestigious Joey Dunlop TT Championship.
Suspension (motorcycle)
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. The most common form of front suspension for a modern motorcycle is the telescopic fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s.
