2023 Husqvarna FX 450

$11,649.00

Benefitting from multiple technical upgrades for 2023, the FX 450 retains its class-leading on-track performance and continues to headline the Husqvarna Motorcycles off-road line-up. With an all-new engine that not only produces a broad spread of usable power, but also positions the engine shaft arrangements at the ideal center of gravity to centralize mass, accentuating the lightweight feel of the FX 450.

Aiding this agile feel is the new chassis which has been developed and manufactured using advanced engineering techniques to offer improved anti-squat behavior for enhanced handling and maneuverability. Retaining the advanced electronics and high-quality components throughout, the FX 450 is complete with a new flatter seat and finished with functional bodywork adorned with white, yellow, and grey graphics inspired by the Swedish heritage of the brand.

Husqvarna FX 450 Features

Engine

The FX 450 engine benefits from advanced engineering techniques to deliver maximum performance. For 2023, the engine is tilted two degrees backwards for significantly improved anti-squat behavior from the chassis while further aiding the centralization of mass for improved overall handling. Servicing of the FX 450 engine is made easier compared to previous models thanks to the addition of service markers on the engine cases.

Cylinder Head

The redesigned SOHC cylinder head is incredibly compact with the camshaft positioned as close to the centre of gravity as possible for significantly improved handling and agility. A new, more durable fine punched cam chain runs on low-friction chain guides for optimal efficiency and improved reliability with a single oil spray jet guaranteeing effective cooling. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.

Cylinder and Piston

The lightweight aluminum cylinder is undoubtedly an engineering masterpiece and features a 95 mm bore with a 63.4 mm stroke. Inside, the CP bridged-box-type piston features anodized annular grooves, adding durability and longer service intervals at a weight of just 327 g. For improved performance, the compression ratio has been increased to 13.1:1 to create an incredible peak power while maintaining its crisp responsiveness.

Frame

The proven chromium molybdenum steel frame is refined for 2023 to reposition rotational masses inside the engine which together with a new shock mounting position, significantly improves anti-squat behavior of the chassis. With optimized wall thickness in high-stress areas improving reliability, the frame continues to offer advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability.

Re-enforced Aluminum Subframe

Made from 60% polyamide and 40% aluminum, the new two-piece subframe for 2023 ensures exceptional strength and durability at an overall weight of just 3.9 lb. The lower subframe spars and frame mounts are manufactured from cast aluminum for significantly improved reliability. The upper section of the subframe is made from injection-molded polyamide to enable specific flex characteristics and ensure a lightweight construction.

Triple Clamps

Matching the new frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability. Customized handlebar flex can be achieved by the new handlebar clamp which offers two mounting options – rubber-damped for less vibration or fixed for enhanced front-end feedback. The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.

Bodywork

Clean, Swedish-inspired design and ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points have been repositioned for 2023 and together with a flatter seat profile, riders can move freely on the motorcycle for total control at all times.

Airbox

Easy access to the TWIN AIR filter is possible without tools, for quicker cleaning and easier maintenance. Precision inlet ducts maximise airflow and offer increased levels of filter protection.

Hydraulic Clutch

The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation and perfect modulation in every condition. Meaning that play is constantly compensated so that the pressure point, and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race focused testing have proven the high-quality, Italian-made Brembo hydraulic systems exceptional reliability.

Wheels and Tires

CNC-machined hubs and high-strength alloy rims by D.I.D are finished in striking black. They feature laser engraved logos and are fitted with a DUNLOP GEOMAX MX33 tyre on the front and DUNLOP GEOMAX AT81 tire on the rear which ensure progressive cornering and superior traction on a variety of terrain.

Exhaust System

Tailored specifically to the FX 450 engine using an innovative 3D design process, the header pipe ensures maximum power across the rev range. The muffler features an aluminum mounting bracket for strength at the lowest possible weight, with an advanced internal construction ensuring excellent noise damping without sacrificing performance.

Cooling System

Manufactured from high-strength aluminum, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air in the most effective way. A large center tube channels coolant through the frame to reduce pressure at this point in the system for a more consistent flow while a new internal thermostat further enhances reliability.

Map Select Switch

A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, and allows riders to toggle between two engine maps. The easy-to-operate map select switch allows racers to quickly alter and set up the engine characteristics on a race by race basis dependent on track conditions and rider preference.

E-Start

As with all 4-strokes in the Husqvarna range, the FX 450 starts with the ease of pressing a button thanks to electric start. A lightweight Li-Ion 2.0 Ah battery is fitted, giving the convenience of electric starting while keeping overall weight to a minimum.

Mapping

For personalised power delivery, the FX 450 has two built-in engine maps as standard. Map 1 offers linear, predictable power, while Map 2 is more aggressive for a sharper throttle response and more explosive power output.
