[item title=”What’s new in Model Year 2017 – In Detail”]
New WP AER 48 front forks
The WP AER 48 front forks are a new milestone in the development of Husqvarna’s motocross models. The 48 mm split air fork features a capsuled air spring and pressurized oil chamber for progressive and consistent damping. By using a capsuled air spring, the fork retains its spring function even in the unlikely event of a pressure leakage. The new forks are safe, lightweight, and easy to adjust through a single air valve and supplied fork pump for pre-load and click adjusters (30 clicks each) for compression and rebound. The system is made up of a set of split-system forks consisting of an air suspension unit and a hydraulic damping unit which benefit from the best in air spring and hydraulic damping characteristics. The new forks offer a weight reduction of 1.66 kg in comparison to conventional fork systems of MY16. The forks are extremely responsive thanks to friction-optimised surface coating on the outer and inner tube surfaces and optimally designed sealing systems. Additionally the wheel travel is increased from 300 mm to 310 mm.
- Capsuled air spring and pressurized oil chamber → progressive and consistent damping
- Easy adjustment → simple clicker adjustment and supplied air pump
- Outer fork tubes → friction optimised coating
- Reduction in weight → 1.66 kg
CNC machined triple clamps
The 22 mm offset black-anodised CNC machined triple clamps feature an integrated rubber damping system that reduces vibrations and increases rider comfort. The triple clamps have been expertly crafted using superior techniques and materials to provide premium quality and reliability while a new upper triple clamp has been redesigned to compliment the new WP AER 48 forks. A 3-way handlebar adjustment is standard and allows for customisable ergonomics.
- Rubber damping on top clamp → reduced vibrations, increased comfort
- CNC aluminium → finest quality and reliability
- Adjustable handlebar position → adjustable ergonomics
New Bar Clamps
The ProTaper handlebar is second to none for function and style. Manufactured to exacting standards, the handlebar features class-leading fatigue resistance while adding minimal weight. For MY17, the lower handlebar clamp has been separated while the top clamp is a bridge-type clamp improving torsional stiffness. The ProTaper logos are chemically applied and are scratch and peel resistant. The large Husqvarna bar pad has optimal impact resistance, while the standard handguards offer maximum roost protection.
- ProTaper handlebar → class-leading function and style
- Oversized bar pad and standard handguards → optimal protection
- New bar clamps → improved torsional stiffness
Map switch, launch control
The MY17 motocross range features a new handlebar map switch on all 4-strokes. Optimised for easy operation, apart from changing between 2 different engine maps, the map switch also activates launch control. With the engine at idle, launch control is engaged by switching once between the selected map and the alternative map, and then back again. When the fuel injection LED flashes, launch control is engaged. 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
The new map switch also operates a traction control feature completely new for MY17. This can be selected to an on or off position from the switch and 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 will register a loss of grip and reduce the amount of power to the rear wheel ensuring maximum traction. This can be a distinct advantage in wet or muddy conditions.
- New traction control feature → optimal traction in all conditions
Dunlop MX3S Motocross tyres that feature the proven “block-within-a-block” design for more progressive cornering and superior grip are fitted as standard. Additionally the FC 250 will now feature a wider 110/90-19 rear tyre as opposed to the 100/90-19 from MY16.
- Developed in top-level AMA Supercross and Motocross → enhanced handling, cornering and steering feel
Modern and functional bodywork in white with traditional Husqvarna blue and yellow accents marks a simplistic yet stylish Swedish design. The ergonomics have been specifically tailored to deliver greater control and comfort, enabling riders to perform at the highest level for extended periods of time. The seat has a low-profile and a high-grip cover for superior comfort and control in all conditions.
- Bodywork → distinctive looks, modern colours and graphics
