FC 250 ROCKSTAR EDITION

01. Finest Componentry

FMF titanium exhaust

As used by Rockstar Energy Husqvarna Factory Racing in AMA Supercross and Pro Motocross competition, the FMF Factory 4.1 RCT silencer is a championship-winning component. Beautifully crafted with a blue anodised titanium body and finished with a carbon fibre end cap, the silencer is considerably lighter than standard, slightly shorter to centralise mass, and delivers a notable boost to overall performance.

Factory Racing wheel set

Superior craftsmanship at its finest. Black anodised EXCEL Takasago rims laced to black CNC-machined hubs using high-quality spokes create an exceptionally strong pair of wheels. Not only incredibly robust, but the weight savings achieved with the Factory Wheel Set contribute to the overall handling of the FC 250 Rockstar Edition thanks to the reduction in unsprung weight.

Factory Racing triple clamps

Featuring a unique clamping design for perfect fork alignment and uncompromised suspension performance, the CNC-machined Factory Racing Triple Clamps are fully adjustable to offer true customisation. With a choice of two offset positions, 20 mm or 22 mm, as well as the option to install the handlebars with rubber mounts for added comfort, or without for a more precise front-end feel, a personalised set-up can easily be achieved.

Pro Taper handlebar

Second to none when it comes to function and style, the ProTaper handlebar is lightweight and incredibly strong. The specifically selected bar bend reduces pressure points on the rider's hands with soft compound ODI lock-on grips offering additional comfort.

Tyres

Delivering best-in-class performance, the new Dunlop GEOMAX MX34 tyres feature a race proven 'block-within-a-block' design for progressive cornering and exceptional grip on a wide variety of racing surfaces.

Bodywork

The contact points of the slim bodywork offer unrestricted movement, which allows riders to perform at their very best for extended periods of time. The high-grip GUTS Racing seat cover is fitted to keep riders firmly in place under hard acceleration. Rounding out the bodywork is the latest Rockstar Energy Husqvarna Factory Racing graphics, which are applied using in-mold technology for a quality and durable finish.

WP XACT front suspension

The high-performance WP XACT 48 mm split air forks feature settings to perfectly match the frame and linkage, ensuring the motorcycle delivers the highest level of comfort, balance, and cornering agility. With oil and air bypasses reducing pressure peaks, in combination with a midvalve damping system, the fork provides exceptional feedback from the front wheel. A hydrostop system creates a more progressive damping force in the final 40 mm of travel for improved bottoming resistance on hard landings.

WP XACT shock absorber

The linkage geometry has been developed to ensure maximum performance from the WP XACT shock and ensures the FC 250 Rockstar Edition is perfectly balanced. Providing 300 mm of rear wheel travel, the shock offers progressive damping, superior energy absorption, and impressive cornering agility.

Frame

Lower in weight than what is found on the standard FC 250, the frame offers improved flex characteristics and stability. The frame itself is expertly crafted from hydro-formed, laser-cut, and robot-welded steel and finished with a premium white powder coating for a true race team look. Constructed with specifically calculated parameters of longitudinal and torsional flex, the chassis provides exceptional rider feedback, energy absorption, and straight-line stability. Additionally, a 2K carbon composite skid plate is fitted to protect the frame and engine from hard impacts.

Subframe

The composite subframe is manufactured using advanced technologies. Constructed with a blend of 60% polyamide and 40% aluminium, the subframe weighs only 1.8 kilograms and is incredibly durable. Designed with the assistance of computational dynamics, specific rigidity has been engineered into the subframe to enhance overall handling and rider comfort.

Swingarm

The aluminium swingarm has been designed to ensure optimal stiffness and durability. Further accentuating the flex characteristics from the chassis, a 22 mm rear axle is fitted. Additionally, the chain guide has a smooth profile and offers outstanding durability.

03. Unparalleled performance

Engine

Engineered to ensure class-leading performance and handling characteristics, all major engine components and shaft arrangements are carefully positioned closer to the centre of gravity to reduce the effects of rotational inertia. The 250 cc 4-stroke engine is also considerably light and tips the scales at just over 26 kg. The FC 250 Rockstar Edition engine is remarkably powerful with impressive torque to suit riders of all abilities.

Cylinder head

For minimal friction and maximum performance, the finger followers inside the DOHC cylinder head are finished with a diamond-like carbon (DLC) coating. These actuate the titanium valves (32.5 mm intake, 27.5 mm exhaust) which, together with the carefully designed combustion chamber, creates class-leading power throughout the rev-range.

Cylinder & piston

The 81 mm cylinder houses a forged bridged-box-type piston made by CP which weighs just 150 g. High strength aluminium is used to manufacture both the cylinder and piston, with both components professionally engineered for outstanding performance and reliability. The stroke is 48.5 mm to match the cylinder and creates a compression ratio of 14.5:1 for exceptional torque and peak performance.

Gearbox

Manufactured by Pankl Racing Systems, the five-speed gearbox is low in weight while offering incredible durability. A Quickshifter sensor fitted to the shift drum ensures smooth upshifts at all times while a low-friction coating on the shifting fork further enhances positive gear changes.

DS clutch

The FC 250 Rockstar Edition features a highly reliable diaphragm steel (DS) clutch which utilises a single diaphragm pressure plate instead of traditional coil springs. Together with a clutch basket engineered from a single piece of CNC-machined steel, the clutch assembly delivers consistent performance and exceptional durability.

Brembo brakes

Brembo brakes deliver class-leading braking performance. With a 260 mm floating front disc, protected by a 2K carbon composite front disc protector, and a 220 mm wave rear disc, the incredible stopping power created allows for late braking, which leads to faster lap times. A new, stronger rear brake pedal tip is less susceptible to damage for continued control.

04. Advanced Electronics

Map select switch

The intuitive handlebar-mounted Map Select Switch allows riders to engage both launch and traction control, enable the Quickshifter, and activate one of two engine maps. The easy-to-operate Map Select Switch allows racers to quickly alter the engine characteristics on a race-by-race basis depending on track conditions and rider preference.

Mapping

For a personalised power delivery, the FC 250 Rockstar Edition has two built-in engine maps as standard, which can be selected and engaged via the Map Select Switch. Map 1 offers linear, predictable power while Map 2 is more aggressive for a sharper throttle response and a more explosive power output.

Quickshifter

The Quickshifter function can be activated via the Map Select Switch and works by interrupting the ignition for a fraction of a second for smooth and precise gear changes, even when the throttle is fully open. To help prevent selecting neutral, the Quickshifter is only active from second gear upwards.

Traction Control

Traction Control on the FC 250 Rockstar Edition is engaged by pressing the ‘TC’ button on the Map Select Switch. Analysing throttle input from the rider and the rate at which engine RPM increases, if the RPM increases too quickly, the Engine Management System (EMS) registers a loss of grip and reduces the amount of power to the rear wheel to ensure maximum traction. This is a distinct advantage in wet and slippery conditions.

Launch Control

With the engine at idle, Launch Control is engaged by pressing the Traction Control and Quickshift buttons simultaneously. Both symbols will start flashing to indicate that Launch Control is activated. Designed for race starts, this technology limits the amount of power to the rear wheel, improving traction, and helps to prevent loss of control under hard acceleration. Once a gear change is made, Launch Control deactivates automatically. Additionally, Quickshift cannot be activated while Launch Control is engaged.

Electric start and Li-Ion battery

Keeping overall weight to a minimum and ensuring fast, reliable starting, the Li-Ion 2.0 Ah battery fitted to the FC 250 Rockstar Edition is approximately 1 kg lighter than a conventional lead battery. Additionally, the electric start and engine stop buttons are located inside the same housing for a simplified experience.
