Description

CYLINDER HEAD

The SOHC cylinder head is incredibly compact and light with the camshaft located as close to the center of gravity as possible, significantly improving handling while its shorter valve timing improves bottom end performance and responsiveness. A new optimized rocker arm design features increased stiffness and reduced inertia on both intake and exhaust.

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 anodized 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 only aerospace grade materials that meet exacting specifications and is manufactured 100% at FMF’s Southern California factory.

PISTON AND CONROD

Replicating the advanced technology used by the Husqvarna motorsport department, a new 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.

CARBON FIBER SUBFRAME

The composite subframe is a design unique to Husqvarna showcasing pioneering technologies and innovation. Using 70% polyamide and 30% carbon fiber, the 2 piece subframe weighs in at just over 2.2 lb. Apart from being remarkably robust, specific care is taken to deliver the perfect rigidity for optimal handling and rider comfort.
