2023 Husqvarna® FS 450

Receiving multiple technical upgrades for 2023 to maintain its class-leading performance on the track, the FS 450 remains the pinnacle machine for supermoto riders. A new engine not only produces a broad spread of controllable power, but positions the engine shaft arrangements at the ideal centre of gravity to vastly benefit manoeuvrability. Aiding this agile feel is the new chassis, which has been developed and manufactured using advanced engineering techniques to assist with repositioning the rotational masses to offer improved anti-squat behaviour for improved handling. Retaining the advanced electronics and high-quality components throughout, the FS 450 is finished with new functional bodywork adorned with white, yellow, and grey graphics, inspired by the Swedish heritage of the brand.

Features may include:

• Powerful engine

The FS 450 engine benefits from advanced engineering techniques to deliver maximum performance. For 2023 the engine is lighter, weighing just 59 lb (26.8 kg), and is tilted two degrees backwards to further centralise mass for enhanced handling and significantly improved anti-squat behaviour from the chassis. Servicing of the FS 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 & piston

The lightweight aluminium 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 anodised 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 to ensure the FS 450 remains firmly at the front of the pack.

• Lightweight frame

The proven chromium molybdenum steel frame is refined for 2023. A new shock mounting, which is no longer connected to the main tube, significantly improves the anti-squat behaviour of the chassis. With optimised 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. The frame is finished off in a premium metallic blue powder coating with redesigned standard frame protectors offering superior protection, durability, and grip in any condition. Additionally, the inclusion of forged brackets on the lower frame rails allows for easy installation of the skid plate, which is available as a technical accessory.

• 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 (1.8 kg). 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.
