Built around Honda's custom - cruiser motorcycle platform, the 1986 Honda CMX 450 Rebel relies on a 447 cc (27.3 cu in) air-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 38 HP (27.7 kW) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 85 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the CMX 450 Rebel measures 185 kg (408 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.87 kg per horsepower). Rider ergonomics and chassis geometry center around a 690 mm (27.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,530 mm (60.2 in) wheelbase engineered for planted straight-line stability. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
