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

WP XACT FRONT FORK

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

CNC-MACHINED TRIPLE CLAMPS

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. Maximum gains in handling are provided by simple offset adjustment of 20 or 22 mm.

• CNC aluminium → finest quality and reliability
• Perfect clamping and alignment → smooth fork action
• Adjustable handlebar position → adjustable ergonomics

BRAKES 

The highest level of quality is guaranteed with class-leading Brembo calipers and levers. The 260 mm floating front and 220 mm solid rear discs deliver superior stopping power instilling confidence in all conditions. A front disc protector is fitted as standard.

• Brembo brake calipers and high-performance discs → superior stopping power with greater control and confidence

PROTAPER HANDLEBARS

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

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
