1997 Yamaha YP 250 Technical Analysis & Specification Breakdown

Positioned in Yamaha's scooter motorcycle lineup, the 1997 Yamaha YP 250 pairs a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 20 HP (14.6 kW) at 6,500 rpm while maximum torque reaches 22 Nm (16.2 lb-ft) at 5,500 rpm. With a specific output of 80 HP per liter and a 1,000 rpm working window between peak torque (5,500 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the YP 250 measures 147 kg (324 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (7.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 700 mm (27.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
