Positioned in Honda's sport motorcycle lineup, the 2023 Honda Grom features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 9.9 HP (7.2 kW) at 7,250 rpm while maximum torque reaches 11 Nm (8.1 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 79.8 HP per liter and a 1,250 rpm working window between peak torque (6,000 rpm) and peak power (7,250 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 Grom measures 101.2 kg (223 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (10.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 761 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,200 mm (47.2 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank paired with a rated consumption of 1.41 L/100 km provides an estimated theoretical range of roughly 426 km (265 miles) between fill-ups.
