Outline of motorcycles and motorcycling
The following outline is provided as an overview of motorcycles and motorcycling:
Motorcycling — act of riding a motorcycle, around which a variety of subcultures and lifestyles have built up.
- Legal definition of motorcycle – a 'powered two-wheel motor vehicle'. Most countries distinguish between mopeds up to 49 cubic centimetres (3.0 cu in) and the more powerful, larger, vehicles known as motorcycles. Scooters do not count as a separate category, and are deemed to be "motorcycles".
- Some motorcycles have paired front wheels, or paired rear wheels, three in all. Motorized tricycles and sidecar outfits are deemed "motorcycles". Most jurisdictions do not consider three-wheeled cars to be motorcycles; but some (including the UK) grant low tax and driving licence exemptions to such vehicles subject to, say, weight and power limits. 
- Motorcycles can be described as all of the following:

Types of motorcycles The design of a motorcycle reflects the purpose for which it is to be used. The main types of motorcycle include:
- Street motorcycle – designed for riding on paved roads; features smooth tyres with a light tread pattern and at least 125
cubic centimetres (7.6
cu in) engine.
Cruiser – mimics the style of American machines from the 1930s to the early 1960s, including those made by Harley-Davidson, Indian, Excelsior and Henderson; models evocative of the early cruisers make up 60% of the U.S. market
- Bobber – usually has had the front fender removed, the rear fender 'bobbed' or made smaller, and all superfluous items removed to make it lighter 
- Chopper – has a longer frame design accompanied by a stretched front end (or rake). To achieve a longer front end, while the frame is being designed, the fabricator tilts the neck of the frame at less of an incline and installs a longer fork.
Sport bike – optimised for speed, acceleration, braking, and cornering on paved roads,
 typically at the expense of comfort and fuel economy in comparison to less specialised motorcycles.
- Café racer – a type of motorcycle that has been modified for speed and good handling rather than comfort. Cafe racers' bodywork and control layout typically mimic the style of Grand Prix roadracers of the 1950s or 1960s with or without fairings. They tend to feature an elongated fuel tank, a small, rearward mounted and humped single seat, and low, race style handlebars mounted on the front forks.
- Streetfighter – a sport bike that is customised by removing the fairing, with other changes that result in an overall more aggressive look  
Touring motorcycle – designed for long-distance touring and heavy commuting; although any motorcycle can be ridden to tour or commute, manufacturers provide specific models designed to address these particular needs
- Sport touring motorcycle – blends performance with long-distance capabilities while providing comfort and relative safety to the rider, and tend to include accessories, such as a trunk or saddlebags for storage, to enhance the touring experience
Standard motorcycle – versatile, general purpose street motorcycle,
 with an upright riding position.
- Universal Japanese Motorcycle – Japanese motorcycle with a transverse air-cooled four-cylinder engine in a conventional tube frame with a dual seat, mostly made in the 1970s and early 1980s
- Cruiser – mimics the style of American machines from the 1930s to the early 1960s, including those made by Harley-Davidson, Indian, Excelsior and Henderson; models evocative of the early cruisers make up 60% of the U.S. market
Custom motorcycle – unique or individually produced in a very limited quantity, as opposed to stock bikes which are mass-produced. Is usually highly stylised or has an unusual frame geometry or engine design. Many styles including café racer, streetfighter, and chopper began as customized motorcycles before manufacturers mass-produced bikes styled after popular custom machines.
- Rat bike – motorcycle maintained at little to no cost, or often of a deliberately exaggerated state of disrepair
Dual-sport motorcycle – type of street-legal motorcycle designed for both on and off-road use
- Enduro motorcycle – motorcycle made specifically for the Enduro sport, with the long travel and medium-hard suspension of a motocross bike enhanced with motorcycle features such as a headlight and quiet muffler to make the bike street-legal for parts of the track
- Motocross motorcycle – a light weight, high power, off-road competition race bike
- Supermoto motorcycle – a dual purpose, single cylinder, light weight bike fitted with equipment better suited to street riding or racing such as 18 inch front wheel and road tyres
- Off-road motorcycle
- Motocross motorcycle
- Track racing motorcycle – customised for track racing, with no brakes and fueled with methanol
- Trials motorcycle – an extremely lightweight design, that lacks seating (designed to be ridden standing up) and that has suspension travel that is short, relative to a motocross or enduro motorcycle
- Small class
- Minibike – sometimes called a mini-moto or pocket-bike, it is a considerably smaller motorcycle; most traditional minibikes use a two stroke engine to turn the rear wheel via a chain
- Mini chopper – mini choppers are scaled-down versions of choppers, and are usually constructed from 1" steel tubing or 3/4" steel black pipe; the tube or pipe is bent and then welded together to get the desired angles and shapes of the frame, which is usually custom made
- Moped – a type of low-powered motorcycle designed to provide economical and relatively safe transport with minimal licensing requirements
- Pit bike – a small off-road motorcycle originally used for riding around the pits or staging area of a motocross race; since the early 2000s, pit bike racing, a sport similar to motocross, has become popular in the United States, especially in Southern California
- Scooter – a step-through motorcycle with a seat, a floorboard, and small or low wheels. Most modern scooter designs have swingarm-mounted engines
- Underbone – a step-through motorcycle with a structural down-tube and conventionally sized wheels, but without a floorboard
- Electric motorcycle – has an electric motor powered by one or more batteries or fuel cells
- Enclosed motorcycle
- Utility motorcycle
- Other designs and variations
- Feet forwards motorcycle – motorcycle on which the rider reclines with his feet positioned ahead of his body
- Related three-wheeled vehicles
- Motorcycle brakes
- Motorcycle chassis – includes the frame and suspension, along with the front forks, of the vehicle.
- Motorcycle frame – provides the strength and rigidity of the motorcycle; all other parts are attached directly or indirectly to the frame
- Suspension – controls the ride and handling of the motorcycle by controlling the rate and distance of the movement of the wheels relative to the frame
- Motorcycle fork – acts as suspension for the front wheel and allows the motorcycle to be steered
- Motorcycle engine – provides the power to propel the motorcycle
- Chain drive – the most common method of transferring power from the engine to the wheels
- Shaft drive – low-maintenance alternative to chain drive, favoured by certain manufacturers, such as BMW Motorrad and Moto Guzzi, and also used on many large touring motorcycles
- Belt drive – low-maintenance alternative to chain drive, favoured by certain manufacturers, such as Harley-Davidson, and on many cruiser motorcycles
- Motorcycle handlebar
- Speedometer – indicates the forward speed of the motorcycle
- Odometer – records and indicates the total distance travelled by the motorcycle
- Tachometer – indicates the rotational speed of the crankshaft in the engine, often also shows an indicated safe limit called a redline

- History of electric motorcycles and scooters
First motorcycle ride – it is generally accepted that the first motorcycle ride was by Gottlieb Daimler's son Paul on a new machine called Einspur ('one track') near Stuttgart in Germany on 10 November 1885.  However, several pioneering engineers and inventors preceded Daimler, mostly with steam engines powering their cycles. These include:
- Lucius Copeland – 19th-century engineer and inventor from Phoenix who demonstrated one of the first motorcycles in 1884
- Louis-Guillaume Perreaux – French inventor and engineer who submitted one of the first patents for a working motorcycle in 1869, the Michaux-Perreaux steam velocipede.
Many pioneering engineers and inventors followed Daimler in using internal combustion engines . These include:

Motorcycle sport – broad field that encompasses all sporting aspects of motorcycling. The various disciplines are not all races or timed-speed events, as several disciplines test a competitor's various riding skills. Riders have raced motorcycles for over a hundred years, with the first official competition recorded as the Paris–Rouen race in July 1894. This was quickly followed by races all over Europe and the US. In 1907, the Isle of Man TT races took over 66 kilometres (41 mi) of the island's roads and has continued since.  Motorcycle sport now takes many different forms, including:
- Freestyle Motocross
- Land speed record – a single rider accelerates over a 1- to 3-mile (4.8 km) long straight track (usually on dry lake beds) and is timed for top speed through a trap at the end of the run. The rider must exceed the previous top speed record for that class or type of bike for their name to be placed on the record books.
- Motoball (Motorcycle Polo) – similar to football, but all players (except goalkeepers) ride motorcycles, and the ball is much bigger.
- Motorcycle trials
- Motorcycle stunt riding
- Category:Motorcycle sport lists
- Motorcycle drag racing
- Road racing
- Pit bike racing – competition sport similar to motocross, using pit bikes
- Track racing
- Motorcycle trials
