[1] They may have special features such as oversized gas tanks, engines tuned for reliability and longevity, sump protectors, and more durable (and heavier) components.

For an enduro event such as endurocross (Enduro-X), these may include:[2] Past and present enduro manufacturers include AJP, ATK, Beta, Bultaco, CCM, Fantic, Gas Gas, Hodaka, Honda, Husaberg, Husqvarna, Indian, Kawasaki, KTM, Maico, Montesa, MZ, Ossa, Penton, Sherco, Suzuki, SWM and Yamaha.

The Greenhorn Enduro was a nationally recognized 500-mile, two-day desert off-road competition that pounded both rider and machine.

In the UK, most enduro clubman bikes were 2-strokes, but many ACU events had a separate class for 4-stroke machines, such as the Honda XR series.

Such 4-strokes tended to be effectively "sporty trail bikes" rather than de-tuned scramblers, but their much improved fuel economy (compared to 2-strokes) meant that they could complete lengthy laps of thirty miles or more without refuelling.

This obviated the need for a back-up team to man refueling stops, allowing 4-stroke clubmen to compete without a support entourage.

[1] This was partially driven by the conversion of MX from 2-stroke to 4-stroke engine designs to comply with regulatory trends, as well as the development of hybrid competition races such as Enduro-X.
