1964 aermacchi chimera 250 Technical Analysis & Specification Breakdown

At the heart of the 1964 aermacchi chimera 250 sport motorcycle, aermacchi relies on a 246 cc (15 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 13.7 HP (10 kW) at 6,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 55.7 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the chimera 250 measures 125 kg (276 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.12 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry.
