Tora

1974 Rockford Tora Technical Analysis & Specification Breakdown

Positioned in Rockford's enduro - offroad motorcycle lineup, the 1974 Rockford Tora relies on a 58 cc (3.5 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 5.8 HP (4.2 kW) at 8,500 rpm while maximum torque reaches 0.5 Nm (0.4 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and shaft drive (cardan) final drive. With a specific output of 100 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 rpm), 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 Tora measures 62.6 kg (138 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 749 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,143 mm (45 in) wheelbase engineered for quick, flickable steering geometry. The 4.1-liter (1.1 US gal) fuel tank paired with a rated consumption of 1.23 L/100 km provides an estimated theoretical range of roughly 333 km (207 miles) between fill-ups, while factory top speed is listed at 81 km/h (50 mph).
