Engineered by Vyrus for the naked motorcycle segment, the 2007 Vyrus 985 C3 V4 utilizes a 999 cc (61 cu in) liquid-cooled v2, four-stroke layout. In factory specification, peak output is rated at 150 HP (109.5 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 150.2 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the 985 C3 V4 measures 157 kg (346 lbs) dry, translating to a power-to-weight ratio of 0.96 HP/kg (1.05 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,375 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry.
