Motorcycles
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).
