1965 Enfield Interceptor Technical Analysis & Specification Breakdown

Engineered by Enfield for the allround motorcycle segment, the 1965 Enfield Interceptor pairs a 736 cc (44.9 cu in) air-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 52 HP (38 kW) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 70.7 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 Interceptor measures 190 kg (419 lbs) wet (curb), translating to a power-to-weight ratio of 0.27 HP/kg (3.65 kg per horsepower). Rider ergonomics and chassis geometry center around a 787 mm (31 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,448 mm (57 in) wheelbase engineered for balanced agility and highway composure. The 17.03-liter (4.5 US gal) fuel tank paired with a rated consumption of 4.28 L/100 km provides an estimated theoretical range of roughly 398 km (247 miles) between fill-ups, while factory top speed is listed at 193 km/h (120 mph).
