Pocketbike Racing
Pocketbikes are small, two wheeled recreational vehicles approximately one-quarter the size of a regular motorcycles, and are powered by two-stroke cycle, two-stroke internal combustion engines of between 40 and 50 cc. Pocketbikes maintain the look of full-sized sport bikes and are known outside of North America for racing on specialty tracks designed for small Power Sport machines. These specialized models, designed for competition, produce up to 17 hp, and have front and rear suspension akin to larger sport bikes. Most consumer models are far less powerful, usually below 3hp, and do not feature suspension, relying on the tires alone for shock-absorption. Weight for most machines are approximately . The usual height is less than , and up to length. The popularity of these types of recreational machines originate from the introduction of Asian Imports to the North American market in late 2003. At the time costing as little as $200 US, these machines were unregulated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minibike
A minibike is a two-wheeled, motorized, off-highway recreational vehicle popularized in the 1960s and 1970s, but available continuously from a wide variety of manufacturers since 1959. Their off-highway nature and (in many countries) typically entirely off-road legal status differentiate minibikes from motorcycles and mopeds, and their miniature size differentiates them from dirt bikes. Traditionally, minibikes have a four-stroke, horizontal crankshaft engine, single- or two-speed centrifugal clutch transmissions with chain final-drive, 4" or 6" wheels and a low frame/seat height with elevated handlebars. Commercially available minibikes are usually equipped with small engines commonly found elsewhere on utilitarian equipment such as garden tillers History While the minibike had precursors in machines such as the Doodle Bug and Cushman Scooters, which share smaller wheels, tubular-steel frames, and air-cooled, single-cylinder engines, those vehicles had larger seat heights a ...

Superbike Racing
Superbike racing is a category of motorcycle racing that employs highly modified production motorcycles, as opposed to MotoGP in which purpose-built motorcycles are used. The Superbike World Championship is the official world championship series, though national Superbike championships are held in many countries, including the United Kingdom, the United States, Japan, Australia and Canada. Superbike racing is generally popular with manufacturers, since it helps promote and sell their product, as captured by the slogan "Win on Sunday; Sell on Monday". Characteristics of Superbike racing motorcycles Superbike racing motorcycles are derived from standard production models, so for a bike to be eligible, the manufacturer must first homologate the model and manufacture the required number of roadgoing machines. While rules vary from series to series, in general the motorcycles must maintain the same profile as their roadgoing counterparts, with the same overall appearance as seen from the ...

Pit Bike
A pit bike is a small recreation, stunt or motocross racing motorcycle. Usually defined as having a horizontal air cooled engine and an open cradle frame. Pit bike history The pit bike evolved from the use of custom-built motorized two wheeled machines (also known as clown bikes) that began appearing during post-war 1940s and 50s pits of racing events. Initially, the term also applied to the use of bicycles or motorcycles used to navigate event staging areas. These hand-built machines were directly responsible for the creation of the Minibike Market. The fairly cheap price and the mobility of Minibikes made them easy to use at racing events. As the minibike market boomed in the 1960s, Honda introduced their own line, and the Honda Z series became popular for filling the role. With the popularity of off-road motorcycles increasing through the 1980s, inexpensive introductory-model motocross and Dual-sport bikes also began to fill this role. While determining the catalyst for pit b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mini Chopper
Mini Choppers are scaled-down versions of custom-built motorcycles known as choppers. Commercially available Mini Choppers are available from various retailers, some utilizing similar production methods to Minibikes, while others use Scooter, Moped sourced parts/engines. Custom Mini Choppers are generally 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. Mini choppers use a variety of engines. One of the most popular is a Base 50 engine, a generic term for Imported single cylinder horizontal 50cc to 140cc 4-stroke engines derived from Honda's line of small motorcycle engines. 50cc (actually 49.5cc) engines offer the advantage of being classified as a Moped or Scooter engine, and many municlities do not require a specific motorcycle license to operate a vehicles with engines sizes of less than 50cc. Larger, vertical engines up to 250cc, developed for the ATV and motorcycle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kart Racing
Kart racing or karting is a road racing variant of motorsport with open-wheel, four-wheeled vehicles known as go-karts or shifter karts. They are usually raced on kart circuit, scaled-down circuits, although some professional kart races are also held on full-size motorsport circuits. Karting is commonly perceived as the stepping stone to the higher ranks of motorsports, with most of Formula One champions including Sebastian Vettel, Nico Rosberg, Ayrton Senna, Max Verstappen, Lewis Hamilton, Michael Schumacher, Kimi Räikkönen, and Fernando Alonso having begun their careers in karting. Karts vary widely in speed and some (known as superkarts) can reach speeds exceeding , while recreational go-karts intended for the general public may be limited to lower speeds. History American Art Ingels is generally accepted to be the father of karting. A veteran hot rodder and a race car builder at Kurtis Kraft, he built the first kart in Southern California in 1956.
