1967 Yamaha 250 Racer Technical Analysis & Specification Breakdown

Positioned in Yamaha's sport motorcycle lineup, the 1967 Yamaha 250 Racer relies on a 250 cc (15.3 cu in) air-cooled twin, two-stroke powerplant. In factory specification, peak output is rated at 44 HP (32.1 kW) at 10,000 rpm while maximum torque reaches 31 Nm (22.9 lb-ft) at 9,500 rpm. With a specific output of 176 HP per liter and a 500 rpm working window between peak torque (9,500 rpm) and peak power (10,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

Rider ergonomics and chassis geometry center around a 1,315 mm (51.8 in) wheelbase engineered for quick, flickable steering geometry. The 22.71-liter (6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 144 km/h (89 mph).
