1961 Ariel Arrow Super Sport 250 Technical Analysis & Specification Breakdown

Engineered by Ariel for the allround motorcycle segment, the 1961 Ariel Arrow Super Sport 250 utilizes a 247 cc (15.1 cu in) air-cooled twin, two-stroke layout. In factory specification, peak output is rated at 20 HP (14.6 kW) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 81 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Arrow Super Sport 250 measures 131.5 kg (290 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 13.6-liter (3.6 US gal) fuel tank paired with a rated consumption of 3.36 L/100 km provides an estimated theoretical range of roughly 405 km (252 miles) between fill-ups, while factory top speed is listed at 126 km/h (78 mph).
