Technologically advanced

• MAP SELECT SWITCH: A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, enable the new Quickshift functionality, and allows riders to toggle between two engine maps. The easy-to-operate map select switch allows racers to quickly alter and set up the engine characteristics on a race by race basis dependent on track conditions and rider preference.
• QUICKSHIFT: The new Quickshift function can be activated or deactivated via the map select switch. The function works only when upshifting, interrupting the ignition for a fraction of a second. This allows upshifting while the throttle is fully open without the use of the clutch. A sensor on the shift drum registers the force from the shift lever, sends the signal to the ECU and the ignition timing is interrupted. To prevent unintended shifts and false neutrals, the function is only active from second gear upwards.
• TRACTION CONTROL: Traction control on the FS 450 is engaged by a button marked ‘TC’ on the map select switch and functions by analyzing 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 or muddy 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 the launch control is active. This function limits the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration. Once a gear change is made, the launch control will deactivate automatically. Additionally, the Quickshift function is deactivated while launch control mode is engaged.
• MAPPING: For personalized power delivery, the FS 450 has two built-in engine maps as standard. Map 1 offers linear, predictable power, while Map 2 is more aggressive for a sharper throttle response and more explosive power output.
• EMS: The new Engine Management System (EMS) is designed to be smaller and lighter while being faster at processing data. It incorporates a new rollover sensor (ROS) which cuts the ignition and shuts off the engine in the event of a severe crash, adding another level of safety to Husqvarna Motorcycles' new generation supermoto.
• HOUR METER: A new hour meter comes with an integrated fuel level indicator, which is visible on the FI status LED, indicating to the rider when the fuel level is becoming low.
• START/STOP SWITCH: The new combined start/stop switch is located on the right side of the handlebar for easy, thumb-operated use. Not only simplifying the starting and stopping of the engine, the removal of a designated stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.
• ELECTRIC START: Along with the benefit of an easy electric starting system, a lightweight Li-Ion 2.0 Ah battery is fitted to the FS 450. The Li-Ion battery weighs approx. 2.2 lb (1 kg) less than a conventional lead battery meaning the convenience of electric starting is delivered while keeping overall weight to a minimum.
