2023 Herald Brat 125 Technical Analysis & Specification Breakdown
Engineered by Herald for the allround motorcycle segment, the 2023 Herald Brat 125 utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14 HP (10.2 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 112.9 HP per liter, 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 Brat 125 measures 147 kg (324 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.5 kg per horsepower). 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. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 112 km/h (70 mph).
