Built around Yamaha's sport motorcycle platform, the 2002 Yamaha TZ 250 pairs a 249 cc (15.2 cu in) liquid-cooled v2, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 86.9 HP (63.4 kW) at 12,250 rpm while maximum torque reaches 50 Nm (36.9 lb-ft) at 11,750 rpm. With a specific output of 349 HP per liter and a 500 rpm working window between peak torque (11,750 rpm) and peak power (12,250 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the TZ 250 measures 104 kg (229 lbs) dry, translating to a power-to-weight ratio of 0.84 HP/kg (1.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 773 mm (30.4 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,345 mm (53 in) wheelbase engineered for quick, flickable steering geometry.
