Positioned in Brixton's allround motorcycle lineup, the 2024 Brixton Cromwell 125 utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 11 HP (8 kW) at 9,000 rpm while maximum torque reaches 9.7 Nm (7.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 88 HP per liter and a 2,500 rpm working window between peak torque (6,500 rpm) and peak power (9,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Cromwell 125 measures 134 kg (295 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.18 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.3 L/100 km provides an estimated theoretical range of roughly 609 km (378 miles) between fill-ups, while factory top speed is listed at 99 km/h (62 mph).
