Supermoto Wheelie
Supermoto is a form of motorcycle racing held on race tracks that alternate between three kinds of track surfaces: the hard packed dirt of flat track, the irregular jumps and obstacles of motocross, and the paved tarmac of road racing. Supermoto was originally conceived by Gavin Trippe in 1979 as a segment of the TV show Wide World of Sports. It was something like an all-star game, in which the best riders from the three separate genres of motorcycle racing could temporarily leave their normal race class to come together and compete for the title of best all around racer. Today supermoto is a distinct genre of its own and riders in the other classes do not routinely cross over into supermoto. Races are commonly held on road racing or medium-sized go-kart tracks with an off-road section in the infield. Most supermoto race tracks have a tarmac size of 50-75% and the remaining percentage of the course is off-road. The dirt sections are usually constructed of packed clay, poly ...

Husqvarna Motorcycles
Husqvarna Motorcycles GmbH (; marketed as Husqvarna) is a Swedish-origin Austrian company which designs, engineers, manufactures and distributes motocross, enduro, supermoto and street motorcycles. The company began producing motorcycles in 1903 at Huskvarna, Sweden, as a subsidiary of the Husqvarna armament firm. Today, Husqvarna Motorcycles GmbH is owned by PIERER Mobility Group. History Prior to 1987 Husqvarna was founded near the town of Huskvarna in Sweden in 1689. The company started out as a maker of muskets, and the Husqvarna logo still depicts a gun sight viewed from the end of the barrel. As with many motorcycle manufacturers, Husqvarna first began producing bicycles in the late 19th century. In 1903, they made the jump to motorcycle manufacturing. The first "Husky" motorcycles used imported engines, and it was not until 1918 that Husqvarna began producing machines built entirely in-house. Around that time they secured a contract with the Swedish Army, and also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilera
Gilera is an Italian motorcycle manufacturer founded in Arcore in 1909 by Giuseppe Gilera (1887–1971). In 1969, the company was purchased by Piaggio. History In 1935, Gilera acquired rights to the Rondine four-cylinder engine. It was, at that time, the world's most powerful engine with . The first across-the-frame 4-cylinder motorcycle was the racer 1939 Gilera 500 Rondine. It had double-over-head camshafts, forced-inducting supercharger and was water-cooled, producing @9000 and had a top speed of . This formed the basis for Gilera' s racing machines for nearly forty years. From the mid-thirties, Gilera developed a range of four-stroke engine machines. The engines ranged from 100 to 500 cc, the most famous being the 1939 Saturno. Designed by Giuseppe Salmaggi, the Saturno was inspired by the pre-war Gilera VTEGS 500 cc “Otto Bulloni” yet was quite different due to its unit construction. After withdrawing from competition in 1957, Gilera changed direction ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slick Tire
A racing slick or slick tyre is a type of tyre that has a smooth tread used mostly in auto racing. The first production slick tyre was developed by M&H Tires in the early 1950s for use in drag racing. By eliminating any grooves cut into the tread, such tyres provide the largest possible contact patch to the road, and maximize dry traction for any given tyre dimension; see Performance. Slick tyres are used on race tracks and in road racing, where acceleration, steering and braking require maximum traction from each wheel. Slick tyres are typically used on only the driven (powered) wheels in drag racing, where the only concern is maximum traction to put power to the ground, and are not used in rallying. Slick tyres are not suitable for use on common road vehicles, which must be able to operate in all weather conditions. They are used in auto racing where competitors can choose different tyres based on the weather conditions and can often change tyres during a race. Performance ...

Superbike
A sport bike (sports motorcycle, or sports bike) is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads. They are mainly designed for performance at the expense of comfort, fuel economy, and storage in comparison with other motorcycles. Sport bikes can be and are typically equipped with fairings and a windscreen to deflect wind from the rider to improve aerodynamics. Soichiro Honda wrote in the owner's manual of the 1959 Honda CB92 Benly Super Sport that, "Primarily, essentials of the motorcycle consists in the speed and the thrill," while ''Cycle World''s Kevin Cameron says that, "A sportbike is a motorcycle whose enjoyment consists mainly from its ability to perform on all types of paved highway – its cornering ability, its handling, its thrilling acceleration and braking power, even (dare I say it?) its speed." Motorcycles are versatile and may be put to many uses as the rider sees fit. In the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Cluer, who was also a horse owner, dreamt of building a first-class race track in Phoenix. Many locals thought Cluer's ambitious project was ill-timed and destined to fail, given that the property was from downtown Phoenix, and that the only way to get there was via a few badly maintained dirt roads. However, he forged ahead and on January 7, 1956, Turf Paradise op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
