Built around Cosmos Muscle Bikes's sport motorcycle platform, the 2011 Cosmos Muscle Bikes 2RWF V8 utilizes a 5735.8 cc (350 cu in) liquid-cooled v8, four-stroke layout. In factory specification, peak output is rated at 350 HP (255.5 kW) at 5,250 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 61 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 2RWF V8 measures 420 kg (926 lbs) dry, translating to a power-to-weight ratio of 0.83 HP/kg (1.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 600 mm (23.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 2,000 mm (78.7 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
