Engineered by Yamaha for the enduro - offroad motorcycle segment, the 1997 Yamaha WR 250Z relies on a 250 cc (15.3 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, maximum torque reaches 46 Nm (33.9 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 68.0 x 68.8 mm (2.7 x 2.7 inches) with a 10.9:1 compression ratio.
On the scales, the WR 250Z measures 114.3 kg (252 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 982 mm (38.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,496 mm (58.9 in) wheelbase engineered for balanced agility and highway composure. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 114 km/h (71 mph).
