Positioned in Cleveland's classic motorcycle lineup, the 2022 Cleveland Ace 400 utilizes a 397 cc (24.2 cu in) oil & air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 42.2 HP (30.8 kW) at 9,500 rpm while maximum torque reaches 35.4 Nm (26.1 lb-ft) at 7,650 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 106.3 HP per liter and a 1,850 rpm working window between peak torque (7,650 rpm) and peak power (9,500 rpm), 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 Ace 400 measures 150 kg (331 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.55 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
