Enduro is a form of motorcycle racing that is run on off-road courses. The main type of the Enduro races are time based, wherein a number of stages are raced in a time trial against the clock. The entire format of the sport revolves around a time based scheme; a time card is used to keep track of the rider’s timings between stages. Every rider must be extremely careful about their arrival at the next stage as they are penalized for arriving early or late for a stage.
Enduro has a very specific set of rules governing its races. These rules specify where and what type of checks can be placed by the race-sponsors. The vigilant placement of checks setup to confuse riders is what appeals to the fans most. Keeping in mind the nature of the sport, Enduro motorcycles are specialized to fit certain needs. These bikes have a deep suspension, and are combined with necessary features required to make them legal, for the public road section of the route. Enduro motorcycles are also fitted with a headlight and taillight/backlight, protective hardware, and an exhaust system that meets local on-road regulations. They also have ‘wide’ gear ratios, and narrower handles for added maneuverability. In recent years, riders have incorporated computers onto their Enduro bikes. These computers are small electronic devices attached to the handle, and are programmed to assist the rider during the race. The pros and cons of using of these electronic devices have been debated upon by various people affiliated to the sport.
The popularity of the sport is fast increasing with The World Enduro Championship being held under the FIM which is the governing body for the sport in Europe. The American Motorcycle Association oversees Enduro’s happenings in the US. Other Enduro events occurring annually are the International Six Days of Enduro (ISDE) and the National championships. |
