Motorcross
Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom. History Motocross first evolved in Britain from motorcycle trials competitions, such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. When organisers dispensed with delicate balancing and strict scoring of trials in favour of a race to become the fastest rider to the finish, the activity became known as "hare scrambles", said to have originated in the phrase, "a rare old scramble" describing one such early race. Though known as scrambles racing (or just scrambles) in the United Kingdom, the sport grew in popularity and the competitions became known internationally as "motocross racing", by combining the French word for motorcycle, ''motocyclette'', or ''moto'' for short, into a portmanteau with "cross country". The first known scramble race took place at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercross
The AMA Supercross Championship (commercially known as Monster Energy AMA Supercross) is an American motorcycle racing series. Founded by the American Motorcyclist Association (AMA) in 1974, the AMA Supercross Championship races are held from January through early May. Supercross is a variant of motocross which involves off-road motorcycles on a constructed dirt track consisting of steep jumps and obstacles; the tracks are usually constructed inside a sports stadium. The easy accessibility and comfort of these stadium venues helped supercross surpass off-road motocross as a spectator attraction in the United States by the late 1970s. From 1974 until 2002 and again from 2008 until 2021, the series was the World Championship of the sport. After losing this status, and with respect to the MXGP holding that discipline's worldwide title, the series, along with the AMA Motocross Championship, will form the SuperMotocross World Championship from 2023.

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or Scavenging (automotive), scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scotland, Scottish engineer Dugald Clerk, who pa ...

Motorcycle Frame
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine. Materials In the early days, motorcycles were little more than motorised bicycles, and consequently frames were tubular steel. While the use of steel tubing is still common, in modern times other materials, such as titanium, aluminium, magnesium, and carbon-fibre, along with composites of these materials, are now used. As different motorcycles have varying design parameters (such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greeves (motorcycles)
Greeves Motorcycles was a British motorcycle manufacturer founded by Bert Greeves which produced a range of road machines, and later competition mounts for observed trials, scrambles and road racing. The original company produced motorcycles from 1952, funded by a contract with the Ministry of Pensions for their Invacar, a three-wheeler for disabled drivers. After many wins in motorcycle trials competitions and developing a successful US export market, the original company ceased trading following a fire in 1977. Richard Deal bought the rights to the Greeves name in May 1999. The new business continues to develop motorcycles and launched the first new Greeves trials bike for 20 years in January 2009, with an all-new British two-stroke 280 cc engine. History The original company founded by Bert Greeves MBE was the Invacar company. Greeves was mowing the lawns of his home in Worcestershire when he had the idea of fitting the lawnmower engine to his disabled cousin's wheelc ...

Bultaco
Bultaco was a Spanish manufacturer of two-stroke motorcycles from 1958 to 1983. In May 2014, a new Bultaco was announced. Origins The origin of the Bultaco motorcycle company dates from May 1958. Francesc "Paco" Bultó was a director of the Montesa motorcycle company, founded in 1944. After several years of steady growth and road racing success, in 1957 Montesa moved to larger facilities. The move was protracted, disrupting production and was followed by a downturn in the Spanish economy. This slump brought to a head disagreements between Bultó and the other senior director Pere Permanyer. As an economy measure, Permanyer (the majority shareholder) felt that the company should withdraw from racing. Bultó, the driving force behind the racing program and responsible for much of the company’s technical expertise was vehemently opposed. Failing to reach a compromise, Bultó decided to leave Montesa to concentrate on his other business interests. Perhaps unsurprisingly, the maj ...
