2027 Husqvarna FX 450

2027 Husqvarna® FX 450

For 2025, a range of technical upgrades takes the overall performance of the class-leading FX 450 even further. Pairing a new frame with revised suspension settings gives this cross country machine a noticeable gain in agility, and the engine shaft arrangements are placed to centralize mass, which ensures a lightweight feel on the move. The 450 cc engine houses a revised clutch, redesigned to provide consistent performance through every ride. A new 6-speed gearbox for 2025, built for cross country style racing with each gear engaging its own specific engine map, gives every rider the benefit of controllable power delivery. Completing the changes are the new silencer and bodywork, plus a seat that sits slightly taller and wider for improved ergonomics.

Features might include:

• Engine

Advanced engineering techniques give the FX 450 engine maximum performance. Light at just 26.8 kilograms, the engine is built to centralize mass for enhanced handling and significantly improved anti-squat behavior from the chassis. Service markers added to the engine cases make servicing the engine simpler.

• Cylinder head

Exceptionally compact, the SOHC cylinder head places the camshaft as near to the center of gravity as possible for unrivaled handling and agility. A hard-wearing, fine-punched cam chain travels on low-friction chain guides for optimal efficiency and reliability, and a single oil spray jet ensures effective cooling. A rocker arm actuates the lightweight valves, whose timing is specifically designed to provide precise levels of torque and throttle response.

• Cylinder and piston

Without doubt an engineering masterpiece, the lightweight aluminum cylinder has a 95 mm bore and a 63.4 mm stroke. Within it, the CP bridged-box-type piston weighs just 327 g and has anodized annular grooves that add durability and longer service intervals. Providing best-in-class performance, the 13.6:1 compression ratio brings incredible peak power while preserving its crisp responsiveness.

• Crankshaft

Specific positioning of the crankshaft harnesses the rotating mass at the ideal center of gravity, which results in a light, agile feel in handling. Accordingly, the crankshaft's inertia is meticulously calculated to provide optimal traction and rideability from the powerful 450 cc engine. A plain big end bearing made up of two force-fitted bearing shells ensures maximum reliability and durability, guaranteeing lengthy service intervals of 90 hours.
