Difference between revisions of "Motorcycle"

The chassis (or frame) of a motorcycle is typically made from welded aluminium or steel (or an alloy) struts, with the rear suspension being an integral component in the design. Carbon-fiber is used in a few very expensive custom frames.

The wheel rims are usually steel or aluminum (generally with steel spokes and an aluminium hub) or 'mag' type cast or machined aluminum. At one time, motorcycles all used spoke wheels built up from separate components (see [[wheelbuilding]]), but, except for [[Dirtbikes]], one-piece wheels are more common now. Performance racing motorcycles often use carbon-fiber wheels, but the expense of these wheels is prohibitively high for general usage.

Motorcycles mainly use [[pneumatic tire]]s ('tyres' in the UK) however, in some cases with off road motorcycles, the tires are filled with a type of mousse which helps prevent punctures. Both types of tires come in many configurations, the most important characteristic of any tire being the [[contact patch]]. That is the small area that is in contact with the road surface while riding.
