Positioned in Husqvarna's cross - motocross motorcycle lineup, the 2018 Husqvarna FC 450 Rockstar Edition features a 449.3 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 63 HP (46 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 140.2 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
Rider ergonomics and chassis geometry center around a 960 mm (37.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
