Technical Overview
2023 Brough Superior Lawrence Dagger Technical Analysis & Specification Breakdown
At the heart of the 2023 Brough Superior Lawrence Dagger allround motorcycle, Brough Superior utilizes a 997 cc (60.8 cu in) liquid-cooled v2, four-stroke layout. In factory specification, peak output is rated at 102 HP (74.5 kW) at 9,600 rpm while maximum torque reaches 87 Nm (64.2 lb-ft) at 7,300 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 102.3 HP per liter and a 2,300 rpm working window between peak torque (7,300 rpm) and peak power (9,600 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 Lawrence Dagger measures 200 kg (441 lbs) dry, translating to a power-to-weight ratio of 0.51 HP/kg (1.96 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,540 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
