At the heart of the 2025 Honda Rebel 300 custom - cruiser motorcycle, Honda features a 286 cc (17.5 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 76.0 x 63.0 mm (3.0 x 2.5 inches) with a 10.7:1 compression ratio.
On the scales, the Rebel 300 measures 165.1 kg (364 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 691 mm (27.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,491 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 11.36-liter (3 US gal) fuel tank paired with a rated consumption of 3.02 L/100 km provides an estimated theoretical range of roughly 376 km (234 miles) between fill-ups, while factory top speed is listed at 175 km/h (109 mph).
