motard sports

Motard is the French word for Biker.
Supermoto, or Supermotard is a cross-over or evolution of motocross and road racing. 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 are typically configured with approximately 70% tarmac and 30% dirt with small jumps but a dirt section is not required. The motorcycles used are frequently custom-created combinations of off-road motorcycles and road-racing rims/tires, known as 'supermotard' bikes. Riders also wear a combination of road race and offroad equipment, normally leathers and a motocross helmet and boots. Unlike normal motorcycle racing, the emphasis lies on slower (<100 mph / <161 km/h), short and twisty tracks, where rider skill matters far more than outright machine performance.
History
Supermoto has its origins in the 1970s where ABC’s Wide World of Sports was the highest-rated sports show in the United States. In 1979, ABC commissioned a made-for-TV event to be included in the series, named Superbikers, whose intention was to find the ultimate all-around motorcycle racer. Superbikers was then manifested as a yearly event run at southern California's Carlsbad Raceway. The show's tarmac-and-dirt courses were intended to draw on talent from the worlds of off-road, flat-track and road-racing. World and National Championship-winning motorcycling greats such as Kenny Roberts and Jeff Ward, whose respective sports at the time were road-racing and motocross, participated in the races. The Superbikers quickly became a huge Nielsen rating contender, running until 1985, at which point ABC was forced to cancel the show due to new management and cuts; its cancellation also initiated a long sabbatical of the sport in the USA. The European racers who participated in the sport at Carlsbad, however, brought it back to Europe with them, where it quickly gained popularity in countries such as France.
2003 signalled the resurrection of the sport in the United States with the birth of the AMA Supermoto championship and with the ESPN X-Games Supermoto championship.
Machines
Prior to the 1990s, supermoto bikes, including the precursor motorcycles used in Superbikers, were converted open-class two-stroke motocross or enduro bikes desired for their lightweight and jumping abilities. The motorcycles currently used for Supermoto racing are predominantly single-cylinder 4 stroke powered dirtbikes with 17" or 16.5" wheels. The 17" rims allow the use of up to 5.5" wide superbike road racing slicks. Slick tires are often hand grooved on the rear tire to facilitate slightly better acceleration on the dirt stretches of a supermoto course. Suspension is lowered and slightly stiffened in comparison with a stock dirt bike, and braking power is improved with oversize front brake rotors and calipers. Despite the lack of trees on supermoto courses, 'bark busters' (hand guards) are frequently added to supermoto bikes due the extreme cornering angles achieved by riders. Hand guards also greatly improve survivability of the brake & clutch levers during a fall making supermoto bikes highly crash resistant and often able to quickly re-enter the fray during a race following a crash.
