01. Unparalleled performance
POWERFUL ENGINE
The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the center of gravity as possible, significantly improving handling and agility. The lightweight valves are actauted via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.
Piston and conrod
Replicating the advanced technology used by the Husqvarna motorsport department, the CP forged box in box piston features a hard anodized compression ring groove with an optimized cam and barrel profile while the new Pankl conrod features a bushing on the piston end reducing friction on the connecting pin resulting in the highest level of performance and reliability.
FMF exhaust system
The Factory 4.1 RCT Muffler incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally and features a blue anodised titanium muffler body with a carbon end cap. In addition, it offers a shorter overall length that is less susceptible to damage and moves the muffler closer to the engine to centralize mass. The Factory 4.1 RCT is constructed from aerospace grade materials that meet exacting specifications and is manufactured 100% at FMF's Southern California factory.
CARBON SUBFRAME
The composite subframe is a design unique to Husqvarna showcasing advanced technologies and innovation. Using 70% polyamide and 30% carbon fibre, the 2 piece subframe weighs in at just over 1 kg. As carbon fibre is renowned for its light weight and high strength, the subframe is remarkably robust with specific rigidity engineered into the subframe to deliver optimal handling and rider ergonomics.
INTERCHANGABLE AIRBOX COVER
Designed with precisely positioned inlet ducts aimed at reducing drag and air flow deformation, the airbox ensures unrestricted airflow with maximum filter protection. The TWIN AIR filter is easily accessed without tools, by simply removing the left side panel for easy maintenance. Offering further performance customisation, the FC 450 ROCKSTAR EDITION is delivered with an additional airbox cover that can be changed without the use of any tools for a sharper throttle response according to rider preference or track conditions.
