Engineered by Herald for the allround motorcycle segment, the 2022 Herald Brat 125 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 9.9 HP (7.2 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 79.8 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
