Husqvarna today released the 2020 FC450 Rockstar Edition. This follows a tradition of offering a special edition prior to the start of the Supercross season.  The official press release follows:

Motocross is embedded in Husqvarna Motorcycles’ celebrated history. Long-standing innovators of the sport, Husqvarna first introduced purpose-built motocross racing motorcycles more than 60 years ago. Since that time the brand has continued to lead in the development of today’s highly specialised motocross and offroad machines.

Legendary international motocross stars such as Torsten Hallman, Mark Blackwell, Kent Howerton, Chuck Sun, Heikki Mikkola, Jacky Martens and Alessio Chiodi have all written successful chapters in Husqvarna’s sporting history. More recently Husqvarna Motorcycles confirmed its commitment to top-end motocross racing when they established the global Rockstar Energy Husqvarna Factory Racing team, in December 2015.

Collaboration with Rockstar Energy Drink has helped Husqvarna Motorcycles enjoy a wealth of success during the last four seasons. Zach Osborne’s 2017 AMA 250SX East, 2017 AMA 250MX and 2018 AMA 250SX East titles and Jason Anderson’s 2018 AMA 450SX Championship have been the stand-out results of this dynamic partnership. In addition, European-based success has come in both the MXGP and MX2 categories where team riders consistently battle for victories in the FIM Motocross World Championship

Rockstar Energy Husqvarna Factory Racing have established a dominant, global force competing at the pinnacle of motocross competition.

Manufactured in limited numbers, Husqvarna’s new FC 450 ROCKSTAR EDITION is a bike built to perform at the highest level. Embracing the highly successful collaboration between Rockstar Energy Drink and Husqvarna Motorcycles, this exciting new model forms the basis of the official Rockstar Energy Husqvarna Factory Racing machine that Jason Anderson, Zach Osborne and Dean Wilson will compete on during the 2020 AMA Supercross Championship.

Showcasing advanced technologies and innovation the composite subframe is a design unique to Husqvarna Motorcycles. Using 70% polyamide and 30% carbon fibre, the two-piece subframe design is incredibly light with a total weight of just over one kilogram. Apart from being robust, specific care is taken to create the perfect rigidity for optimal handling and rider comfort.

  • Carbon fibre composite construction → lightweight and robust

  • Specific rigidity → optimal handling and comfort


The updated WP XACT 48 mm split air forks feature extended oil and air bypasses to improve comfort by reducing pressure peaks. Damping is easily adjusted via the single air pressure valve for pre-load (on the left leg), using the supplied fork pump. Compression and rebound fine-tuning are handled with tool-free easy access clickers with 30 clicks (on the right leg). Standard on the FC 450 ROCKSTAR EDITION, a mechanical holeshot device compresses the front forks and minimises front wheel lift off the start.

  • Precision engineering by WP → highest performance levels

  • Extended oil and air bypass → improved comfort by reducing pressure peaks

  • Easy access clicker dials → simple and fast clicker settings

  • Mechanical holeshot device standard


Made from high-grade aluminium, the CNC-machined triple clamps feature optimally tuned steering stem stiffness, perfect alignment of the fork tubes and precise geometry of the fork clamps to ensure highly responsive and smooth fork action.

  • Magura hydraulic clutch → perfect action in every condition


Optimised for easy operation the map switch offers the possibility to change between two different engine maps and activates launch control. With the engine at idle, launch control is engaged by pressing both TC and MAP buttons simultaneously for about two seconds. The LED lamp will blink continuously meaning the system is active. This function limits the amount of power to the rear wheel, improving traction and preventing loss of control under hard acceleration.

  • Standard handlebar map switch → alter engine characteristics according to conditions and rider preference

  • Launch control → maximum traction for perfect starts


Traction control can be selected to an on or off position from the switch. It functions by analysing throttle input from the rider and the rate at which RPM increases in the engine. If the RPM increases too quickly, the EMS registers a loss of grip and reduces the amount of power to the rear wheel ensuring maximum traction. This can be a distinct advantage in wet or muddy conditions.

  • Traction control → optimal traction in all conditions


The SOHC engine is the perfect example of the advanced engineering techniques used by Husqvarna Motorcycles. It delivers amazing peak power with an overall weight of just 27.3 kg.
