COMPETITION MOTORCYCLES
There are many types of motorcycle sport and in each, a specialist machine has evolved to perform to specific requirements.
Races take place on roads or tracks or "off-road", in fields, dirt tracks, and even the desert. "Grand Prix" world championships in road-racing exist for 125cc, 250cc, and 500cc classes, as well as for sidecars. The latest racing sidecars have more in common with racing cars than motorcycles.
The rider and passenger operate within an all-enclosing, aerodynamic fairing. The Suzuki RGV500 shown here, like other Grand Prix machiners, carries and advertising, which promotes the manufacturer and helps to cover the cost of developing motorcycle technology.
In Speedway, which originated in the US in 1902, motorcycles operate without brakes or a gearbox. Off-road competition motorcycles have less emphasis on high power output.
In Motocross, for example, which is held on rough terrain, they must have high ground clearance, flexible long-travel suspension, and tyres with a chunky tread pattern, to allow them to grip in sand or mud.
