Built around Yamaha's cross - motocross motorcycle platform, the 1981 Yamaha IT465 relies on a 465 cc (28.4 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 46 HP (33.6 kW) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 98.9 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the IT465 measures 119.7 kg (264 lbs) dry, translating to a power-to-weight ratio of 0.38 HP/kg (2.6 kg per horsepower).
