2025 Honda Gb350S Technical Analysis & Specification Breakdown
At the heart of the 2025 Honda Gb350S motorcycle, Honda features a 348 cc engine configuration. In factory specification, maximum torque reaches 29 Nm, transferring power to the rear wheel through a 5-speed manual transmission gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 70 mm x 90.5 mm with a 9.5 compression ratio.
On the scales, the Gb350S measures 178 kg (392 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 600 km (373 miles) between fill-ups.
