Technologically Advanced

• MAP SELECT SWITCH: The intuitive handlebar-mounted Map Select Switch allows riders to activate Launch and Traction Control, enable the Quickshifter, 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.
• QUICKSHIFTER: The Quickshifter function can be activated or deactivated via the Map Select Switch and works by interrupting the ignition for a fraction of a second when upshifting. A sensor on the shift drum registers the force from the shift lever, sends a signal to the ECU, and ensures smooth gear changes, even when the throttle is fully open. To prevent unintended shifts, the function is only active from second gear upwards.
• TRACTION CONTROL: Traction Control on the FX 350 Heritage model is engaged by pressing 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.
• MAPPING: By using the Map Select Switch, the engine characteristics can be tailored to modify the power delivery according to rider preference, conditions, and terrain. It has two settings that can be safely toggled between while riding, by simply pressing a button on the handlebar-mounted Map Select Switch. Map 1 (white) is the standard option, that delivers linear, predictable power, while map 2 (green) is more aggressive with improved throttle response and sharper, explosive power output.
