Husqvarna has revealed its 2019-and-a-half FC 450 that will form the basis of the factory machine Jason Anderson will use to defend his AMA Supercross crown and is likely to be the bike that the 2020 production machine is based on.
AMA rules state all bikes must be production based, so Husqvarna and KTM annually make a batch of bikes with the latest technology to use in Supercross and legally have to offer a minimum of 450 for sale. These bikes often have the sane technology as the forthcoming standard bikes.
Last year Anderson had a 450 with the new frame, bodywork, engine and suspension that made it onto the 2019 production machine. The bike was totally different to the stock 2018 450. But the new Rockstar Edition does not look to have any massive, obvious changes.
Husky’s official release says:Husqvarna Motorcycles are proud to launch the FC 450 ROCKSTAR EDITION model year 2019, a thrilling new production model that forms the basis of the bikes to be used by Rockstar Energy Husqvarna Factory Racing’s AMA Supercross Champions Jason Anderson and Zach Osborne throughout the 2019 season.
Collecting feedback from the Rockstar Energy Husqvarna Factory Racing team and their championship-winning riders, Husqvarna Motorcycles engineers have combined this competition data with extensive testing and development to introduce a list of vital upgrades. The new FC 450 ROCKSTAR EDITION features the latest in engine and chassis developments, ensuring this state-of-the-art machine offers unrivalled on-track performance.
This second edition of the FC 450 ROCKSTAR EDITION continues to pay tribute to a highly successful collaboration between Husqvarna Motorcycles and their global partner Rockstar Energy Drink. Produced in limited numbers, the all-new FC 450 ROCKSTAR EDITION will be available worldwide from January onwards.
BUILT FOR COMPETITION
At the leading edge of motocross development, Husqvarna Motorcycles introduce a series of considered upgrades to the FC 450 ROCKSTAR EDITION. With the distinctive bodywork receiving new graphics, the end result clearly showcases the direction of Husqvarna Motorcycles’ pioneering development.
Replicating the advanced engine technology used by the Rockstar Energy Husqvarna Factory Racing team in their championship-winning machines, the FC 450 ROCKSTAR EDITION model year 2019 features a new CP forged box-in-box piston and a new Pankl conrod. Providing reduced friction, the new piston and conrod ensure the SOHC engine continues to offer the highest level of performance and reliability available in the market today.
The all-new FC 450 ROCKSTAR EDITION machine features FMF Racing’s Factory 4.1 RCT silencer. The new exhaust system has a blue anodized titanium body and a carbon end cap. In addition, it offers a shorter overall length that makes it less susceptible to damage. Moving the silencer closer to the engine also aids mass centralisation.
Made from high-grade aluminium, the all-new CNC-machined triple clamps feature optimally tuned steering stem stiffness as well as perfect alignment of the fork tubes for highly responsive and smooth fork action. Maximum gains in handling are provided by easy offset adjustment between 20 or 22 mm.
The list of upgrades is completed with a new set of anodized D.I.D DirtStar rims and anodized machined hubs. Offering maximum weight savings, this premium-quality combination ensures maximum strength and reduced weight. Tailored to the needs of every aspiring motocross racer, the new FC 450 ROCKSTAR EDITION features a carbon fibre reinforced engine protector and a mechanical holeshot device as standard.

The Factory 4.1 RCT is constructed from only aerospace grade materials that meet exacting specifications.
- • FMF Factory 4.1 RCT silencer → light weight, optimal performance
- • Shorter overall length → centralized mass, less susceptible to damage
ELECTRIC START WITH LI-ION BATTERY
Along with the benefit of an easy electric starting system, a Li-Ion 2.0 Ah battery is fitted to the FC 450 ROCKSTAR EDITION. The Li-Ion battery weighs approximately one kilogram less than a conventional lead battery, offering the convenience of electric starting while overall weight is being kept to a minimum.
- • Electric starter → easy starting when time is critical
- • Li-Ion battery → lightweight, 1 kg lighter than a conventional battery
NEW D.I.D DIRTSTAR RIMS
Black high-strength anodized rims by D.I.D are coupled to CNC-machined hubs using lightweight spokes and blue anodized aluminium nipples to offer maximum weight savings and optimised handling and stability in challenging terrain.
- • Lightweight but strong and reliable construction → minimum unsprung weight
The lightweight 5-speed gearbox produced by PANKL ensures the highest level of durability and reliability. The gear lever features a design that prevents dirt build-up and keeps the lever tip in its original position even in the toughest conditions. An advanced gear sensor selects a specific engine map tailored for each gear.
- • 5-speed gearbox → smooth and precise shifting
- • Integrated gear sensor → specific engine maps for each gear
MAGURA HYDRAULIC CLUTCH
The reliable, high quality, German-made clutch system guarantees even wear, near maintenance-free operation and perfect action in every condition. Clutch play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time.
- • Magura hydraulic clutch → perfect action in every condition
MAP SWTICH & LAUNCH CONTROL
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. Mass-centralisation is key in the engine design, enabling chassis engineers to position the engine closer to the centre of gravity for greatly improved handling and manoeuvrability. The FC 450 ROCKSTAR EDITION model year 2019 features a new CP forged box-in-box piston and a new PANKL conrod. Providing reduced friction, the new piston and conrod ensure the SOHC engine continues to offer the highest level of performance and reliability available in the market today.
- • Mass centralisation → improved handling and reliability
- • New CP box-in-box piston and PANKL conrod → reduced friction and increased durability
Advanced bodywork provides unparalleled comfort and control, enabling riders to perform at the highest level, while the Rockstar Energy Husqvarna Factory Racing team graphics provide the new FC 450 ROCKSTAR EDITION with race-winning aesthetics straight out of the showroom.
- • Ergonomics → confidence-inspiring riding position in all riding situations
- • Comfort → riding at the highest level for extended periods of time
