New 2023 Husqvarna FX450

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 centre of gravity to centralise 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 behaviour for enhanced handling and manoeuvrability. 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.

Features may include:

• 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 behaviour from the chassis while further aiding the centralisation 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. Lighter for 2023, the 450 cc 4-stroke engine weighs just 59 lb.

• 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.

• Polyamide-reinforced aluminium subframe

Made from 60% polyamide and 40% aluminium, 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 aluminium for significantly improved reliability. The upper section of the subframe is made from injection-moulded 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. Customised 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.
