Engineered by ATK for the enduro - offroad motorcycle segment, the 1987 ATK NX 250 utilizes a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout.
On the scales, the NX 250 measures 128 kg (282 lbs) dry. Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,473 mm (58 in) wheelbase engineered for balanced agility and highway composure. The 8.7-liter (2.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
