Engineered by AJS for the enduro - offroad motorcycle segment, the 2008 AJS YX-R-125 utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 57.0 x 48.8 mm (2.2 x 1.9 inches).
On the scales, the YX-R-125 measures 125 kg (276 lbs) dry. Rider ergonomics and chassis geometry center around a 865 mm (34.1 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,434 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
