2017 Husqvarna FX 450 Technical Analysis & Specification Breakdown

At the heart of the 2017 Husqvarna FX 450 enduro - offroad motorcycle, Husqvarna relies on a 449.3 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. 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.

On the scales, the FX 450 measures 101.6 kg (224 lbs) dry, translating to a power-to-weight ratio of 0.62 HP/kg (1.61 kg per horsepower). Rider ergonomics and chassis geometry center around a 970 mm (38.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,482 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
