Built around Brixton's allround motorcycle platform, the 2021 Brixton Sunray 125 features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. 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 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 Sunray 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). The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 560 km (348 miles) between fill-ups, while factory top speed is listed at 99 km/h (62 mph).
