The machines used are customised motorcycles, these have no brakes and are fuelled with methanol. Speedway also uses motorcycles with no gears or rear suspension. | The machines used are customised motorcycles, these have no brakes and are fuelled with methanol.

The use of methanol provides an increased compression ratio to the engine resulting in higher speeds (approx 80mph when cornering) although the skill of Track Racing lies in the overall ability of the rider to control his motorcycle when cornering and thus avoid losing places through deceleration. | The use of methanol provides an increased [[compression ratio]] to the engine resulting in higher speeds (approx 80mph when cornering) although the skill of Track Racing lies in the overall ability of the rider to control his motorcycle when cornering and thus avoid losing places through deceleration. | ||

Speedway racing takes place on a flat oval track usually consisting of dirt or loosely packed shale, competitors use this surface to slide their machines sideways into the bends using the rear wheel to scrub-off speed while still providing the drive to power the bike forward and around the bend. | Speedway racing takes place on a flat oval track usually consisting of dirt or loosely packed shale, competitors use this surface to slide their machines sideways into the bends using the rear wheel to scrub-off speed while still providing the drive to power the bike forward and around the bend. | ||

Originating in New South Wales, Australia in the 1920s, there are now both domestic and international competitions in a number of countries including the [[Speedway World Cup]] whilst the highest overall scoring individual in the [[Speedway Grand Prix]] events is pronounced the Speedway world champion. | Originating in New South Wales, Australia in the 1920s, there are now both domestic and international competitions in a number of countries including the [[Speedway World Cup]] whilst the highest overall scoring individual in the [[Speedway Grand Prix]] events is pronounced the Speedway world champion. | ||
