Enduro is a form of motorcycle sport run on courses that are predominantly off-road. Enduro consists of many different obstacles and challenges. The main type of enduro event, and the format to which the World Enduro Championship is run, is a time-card enduro, whereby a number of stages are raced in a time trial against the clock.

Time-keeping enduros[edit]

In a traditional time-keeping enduro, riders leave together in groups or rows, and each row starts at a certain minute. The object of the event is to arrive at pre-defined locations according to a strict schedule. Early or late arrivals result in the riders' scores being penalized. Throughout a day there will also be allocated periods for refuelling and servicing the machine. Penalties apply for not meeting defined times or for outside-assistance when not permitted.[1]

A world championship course must be at least 200 km and a maximum of 30% of its length can be on asphalt roads.[1] American Motorcycle Association (AMA) rules are different with respect to course length and other variables (i.e. average speed, terrain type, etc.). The rules of the regional sanctioning body can also affect the rules for a particular enduro course.[1]

Enduros vs. rallies[edit]

Casual observers often confuse the two different types of events, enduros and rallies, but within the international off-road motorcycle community, the term enduro refers specifically to time keeping events. Rallies, on the other hand, are simply a course that has a start and finish, and the competitors try to race to achieve the fastest time from start to finish. Such courses may be shorter than the total length of the race, in which case the course is repeated several times, with each repetition being referred to as a lap. Such courses may also be very long such that competitors never cover the same ground twice.

Certainly part of the confusion stems from the fact that rallies and enduros share two pronounced qualities; they are usually lengthy compared to most forms of motorsport racing and they cover varying off-road terrain, usually without repeating any section of the terrain in the course of an event. Examples of such rallies include the Baja 500 and Baja 1000, which are promoted and administered by SCORE International and are amongst the most well known long-distance off-road races. Off-road races that span multiple days and that have different types of stages, some that are timed and others that are not, are generally referred to as rallies (or rallyes) or rally raids (a term widely used in the United Kingdom that is synonymous with off-road rally) such as the Dakar Rally.

An enduro motorcycle is specialized for the nature of the sport, with the deep suspension of a motocross bike combined with the features required to make it legal for the public road portions of the course. Engines are generally single-cylinder two-stroke between 125 and 300 cm³ (cc), or four-stroke between 250 and 650 cm³ (cc).

The World Enduro Championship and several other championships currently categorize enduro motorcycles into three classes; Enduro 1 (100 to 125 cc 2-stroke or 175 - 250 cc 4-stroke), Enduro 2 (175 to 250 cc 2-stroke or 290 - 450 cc 4-stroke) and Enduro 3 (290 to 500 cc 2-stroke or 475 - 650 cc 4-stroke).

Major events in the enduro calendar include the World Enduro Championship (WEC), the International Six Days Enduro (ISDE) and several national championships. The world governing body for enduro is the Fédération Internationale de Motocyclisme (FIM). In the United States, the national governing body is the American Motorcycle Association (AMA). In the United Kingdom, the national governing body is the Auto-Cycle Union.

World Enduro Championship[edit]

The World Enduro Championship (WEC) was started in 1990, replacing the European Enduro Championship, which had been contested since 1968. The championship is run under the FIM and generally consists of around eight or nine Grands Prix spread around the globe. These events are split into two days (and two different races), from which points towards the world championship are awarded. Each round includes a motocross test and an "extreme test", in addition to the enduro test.

In the 2008 season, Honda's Mika Ahola won the Enduro 1 class, Yamaha's Johnny Aubert took the enduro 2 class and KTM's Samuli Aro won his fifth title in the Enduro 3 class.


The International Six Days Enduro (ISDE) has been held since 1913, and it is the oldest off-road event in the FIM calendar. The event brings together the best riders to represent their national team, and it is often referred to as the "World Cup of Enduro" or the "Olympics of Motorcycling".

AMA national and regional events[edit]

The American Motorcycle Association is the primary sanctioning body for motorcycle races of all types in America. AMA series are often analogous to FIM series. The East Coast Enduro Association has multiple classes divided by bike type and rider demographic that allow a qualified rider to choose a class to compete in.

Each Class (A, B, C) is divided into sub-classes depending on machine type. Some examples include "C 4-stroke," "C-Veteran," "B 2-Stroke Light," "B 2-Stroke Heavy," etc... Generally speaking, there are rewards at both the event and season level for each sub-class (i.e., "I was the B 2-Stroke Light winner at this event...").

The following is a list of bike classes:

  • Class AA - The most accomplished level of rider, same as "Class A,", but who competes for points as part of the AMA National Enduro Championship. For example, Mike Lafferty, who is the 7 time AMA National Champion, competes in the AA class.
  • Class A - These are also the fastest riders, but they are not competing for points as part of the National Championship. Their awards are restricted to the AMA Region in which they compete. They are amateur participants, although they possess a skill level comparable to many of the AA riders.
  • Class B - This is the second level of rider skill (one step up from the entry level C-class). Riders are "promoted" by the AMA when they have received a certain number of points (promotion points are different from the points that are awarded during a race; points during a race are bad, as the goal is to finish an event with as close to 0 points as possible, whereas title/promotion points are awarded at the end of each event depending on how well each rider performed - the dual use of the nomenclature "points" can often be confusing to outside observers, because the connotation of having points during an event is negative, whereas the connotation of having points relative to a rider's standing in a series is generally positive).
  • Class C - This is the entry level where all new riders begin. All riders start off as C-Class riders and if they continue to participate in and finish events they will likely be promoted to B-class after 2 or 3 seasons. Exceptional riders will make the leap to B-Class after their first season because they will have accumulated the requisite points quickly enough.

Because of the variety of awards that are possible, riders are sometimes accused of sandbagging.

The popularity of enduro varies widely by continent, country, region, and even by event type. Some popular events are loosely categorized as enduros even though they fall into a category of off-road racing that is known as rally racing or rally raid.


In addition to rallying and rally raids, there are other off-road races that are very similar to enduros but that vary in that they are not necessarily timekeeping events and in that they are often sanctioned by other bodies than the primary enduro sanctioning bodies.

One example in the USA is the Grand National Cross Country, which more closely resembles hare scrambles, such as the Austrian Erzberg Rodeo than Enduros, but is on a shorter course of perhaps a few miles/kilometers in length that is repeated for several laps. GNCC is famous for the high level of ATV (four-wheeled off-road vehicles) competition in addition to motorcycle competition.

Endurocross or indoor enduro is a variation of enduro held indoors. Riders must complete as quick as possible a course with obstacles similar to those in enduro.
