Engineered by Vyrus for the naked motorcycle segment, the 2017 Vyrus 987 C3 4V features a 1198.4 cc (73.1 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 167 HP (121.9 kW) while maximum torque reaches 135 Nm (99.6 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 139.4 HP per liter, 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 987 C3 4V measures 155 kg (342 lbs) dry, translating to a power-to-weight ratio of 1.08 HP/kg (0.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 295 km/h (183 mph).
