Sometimes manufacturers like to put most of their eggs in one basket. For example: Kawasaki has an awesome motocross model lineup, but there are no real comparable 250 or 450 cross-country or trail bike models to select from. Husqvarna (and KTM for that matter) is different because the company builds bikes for not only the avid motocrosser, but for the hardcore off-roader, too. And like the Husqvarna MX bikes, the cross-country bikes share all the same high-end componentry, though they’re tuned a little differently.
The 2019 Husqvarna cross-country model lineup doesn’t take a backseat to its track-focused siblings and has received all the same love and updates – there’s no favoritism here. These off-road models are essentially high-performing motocrossers with slightly softened suspension and trail-specific dampening, 18-inch rear wheels (instead of 19), larger fuel tanks for extended range, wider ratio 6-speed transmissions and hand guards. There’s virtually no where these bikes can’t go, as evidenced by Graham Jarvis, multi-time enduro world champion and Erzberg Rodeo winner, and many other top professional and amateur riders alike.
Husqvarna is out for blood and is asserting itself as one of the top, if not the premier off-road manufacturer in the industry. Husqvarna spells it all out below.

Showcasing Husqvarna Motorcycles’ pioneering design direction in the competition bike segment, a fresh new bodywork design offers advanced ergonomics for optimum comfort and control.
The hydro-formed, laser-cut and robot-welded frame is expertly crafted. Constructed with specifically calculated parameters of longitudinal and torsional flex, the MY19 frames feature newly designed sections that bring an increase in rigidity. This results in improved rider feedback, energy absorption and stability. New aluminum lateral engine head stays contribute to precise cornering and reduced vibration levels. Additionally, the 4-stroke frames feature new precision-casted head stay mounts and brackets for mounting an optional skid plate that will be available in the accessories line. The frame is finished off in a premium blue powder coating and standard frame protectors that guarantee superior protection and durability.
Showcasing pioneering technologies and innovation, the composite subframe is a design unique to Husqvarna Motorcycles. Using 70% polyamide and 30% carbon fiber, the new 2-piece subframe design (previously 3-piece) saves 250 g for a total weight of just over 1 kg (2.2 lbs). In addition to being robust, specific care has been taken to create the perfect rigidity (vertical stiffness +30%) for optimal handling and rider comfort.
The hollow, cast aluminum swingarm is designed to offer optimal stiffness and reliability at the lowest possible weight. For MY19, the chain adjustment slot has increased by 5 mm, extending the total wheelbase adjustment length for improved straight-line stability on faster tracks and over whoops.
The ultra-lightweight WP AER 48 front fork is a 48 mm split air fork featuring a capsuled air spring and pressurized oil chamber for progressive and consistent damping. The forks feature a new setting to match the new frame stiffness and are adjusted via the single air pressure valve for pre-load on the left and with easy-access clickers for damping adjustments on the right (compression on the top and rebound on the bottom, up to 30 clicks each). Additionally, the air pump needed to adjust the air pressure in the fork is provided as standard.
The 22 mm offset CNC-machined triple clamps feature an integrated rubber damping system that reduces vibration and increases rider comfort. They have been reshaped and stiffened to work in concert with the increased longitudinal rigidity of the frame and the new suspension set-up, improving both handling and stability. A three-way handlebar adjustment is standard and allows for customizable ergonomics. Additionally, the front number plate integrates a yellow triple clamp guard, which covers the lower triple clamp and protects it from wear.
Featuring a new main piston and updated settings, the WP DCC shock has been developed to match the linkage system, frame geometry, increased frame rigidity and the new front fork set-up. The shock has been further perfected to provide advanced damping characteristics while keeping a compact and lightweight design. With a pressure balance inside the shock, offering consistent damping, and full adjustability of both high and low speed compression, the system offers the greatest possible traction and absorption and superior rider comfort and handling. Further, the rear wheel travel is 300 mm.
The Husqvarna Motorcycles frame features an innovative, self -cleaning footpeg mount which prevents the build-up of dirt collected through deep ruts or muddy terrain. As a result, the footpeg will spring back into its original position even in the toughest conditions.
The reliable, high-quality, German-made clutch system guarantees even wear, near maintenance-free operation and perfect action in every condition. With the play being constantly adjusted, the pressure point and function of the clutch remain identical in cold or hot conditions and over time.
The Magura braking system offers the highest level of braking performance while specifically tailored to deliver a sensitive and modulated feel. The 260mm front and 220mm rear waved brake discs keep weight to a minimum and offer complete braking confidence.
The ProTaper handlebar is second to none for function and style. Manufactured to exacting standards, it features class-leading fatigue resistance while adding minimal weight. A new bend for all MY19 models further increases comfort by improving the pressure point on the rider’s hands. The standard handguards offer maximum roost protection.
The ODI lock-on grip on the left side does not require gluing, while on the right, the vulcanized grip features an innovative integrated throttle mechanism. The assembly has easy free-play adjustment and, by changing a cam, throttle progression can be altered.
Designed for easy operation, the standard map switch on all 4-strokes activates launch control, selects between two engine maps and activates the traction control feature. Both traction control and launch control feature updated settings for MY19. These offer improved traction off the start and on slick tracks and work simultaneously – when launch control is activated – to offer maximized benefits. 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. The map switch offers selection between a standard map and more powerful one.
Traction control can be selected to an on or off position from the handlebar map switch and functions by analyzing throttle input from the rider and the rate at which RPM increase in the engine. If the RPM increase too quickly the EMS will register a loss of grip and reduce the amount of power to the rear wheel, for maximum traction. This can be a distinct advantage in wet or muddy conditions.
The Keihin EMS is specifically designed to be smaller, lighter and faster at processing data. It integrates launch control for perfect starts, selectable engine maps via the switch on the handlebar as well as traction control. Combined with the new gear sensor, power delivery is tailored for each gear.
All MY19 FC machines are equipped with a 44 mm Keihin throttle body featuring an innovative injector positioning that offers the most efficient flow into the combustion chamber and improved atomization. To ensure optimal throttle response, the throttle cable is mounted directly and without a throttle linkage. This set-up provides more immediate throttle response and feeling. A new throttle cable routing eases maintenance allowing the cable to be removed more easily.
All 4-stroke exhaust systems are expertly crafter to deliver the best possible performance at the lowest possible weight. For MY19 the 4-stroke header pipes feature a new flow designed resonance chamber integrated within them. The new header pipes also feature a new joining position allowing them to be removed without detaching the rear shock. The new silencers are shorter and more compact while delivering the same damping volume and noise levels. The units are crafted from lightweight aluminum and are stylishly finished off with a new anodized coating that proudly carries the Husqvarna Motorcycles logo. All 2-stroke mufflers feature new internals with less dense packing material offering more efficient noise damping. Together with a new aluminum mounting bracket, there is a weight saving of 300 g.
The radiators are expertly crafted using high-strength aluminum. CFD (computational fluid dynamics) technology is used to channel air through the radiators more efficiently for optimal cooling in any condition. Channeling coolant through the frame allows for improved cooling and eliminates the need for additional hoses. New to the system for MY19 is a 4 mm larger center tube that runs through the frame. The new tube reduces the pressure at this point in the system allowing for a more consistent coolant flow. Additionally, the radiators are mounted 12 mm lower, improving the center of gravity while sophisticated radiator protectors not only protect the radiators from flying debris but also act as a brace in the event of an impact.
The airbox is designed with precisely positioned inlet ducts to prevent air deformation, ensuring maximum airflow and filter protection. The air filter is easily accessed, without tools, by removing the left side panel. Easy maintenance is guaranteed with the Twin Air filter and filter cage design that features a simple fail proof mounting system for easy and accurate filter installation.
Black high-strength alloy rims by D.I.D. are coupled with CNC-machined hubs using lightweight spokes and silver anodized aluminum nipples. For MY19, the spoke nipples have a new design that reduces the frequency of checks or tightening.
Dunlop Geomax tires are fitted as standard with an 18-inch rear sizing for off-road performance.
The polythene fuel tanks feature improved ergonomics and incorporate a threaded filler cap and an integrated fuel pump on the 4-stroke range. The fuel pump is optimized with a new internal line routing from the pump to the flange for improved fuel flow. For MY19, the external fuel line has moved inward and is less exposed and susceptible to damage.
