Manufactured in two pieces and designed for compactness, the header pipe allows the exhaust system to be removed without removing the rear shock.
• COOLING SYSTEM: Manufactured from high-strength aluminum, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air through them in the most effective way. A large center tube through the frame reduces pressure at this point in the system for a consistent coolant flow, while an internal thermostat further enhances reliability. A threaded radiator cap allows for easy inspection of the coolant level before each ride.
• FUEL TANK: The 2.24-gallon (8.5-liter) fuel tank integrates neatly within the ergonomic bodywork and features a strong rubber cushion beneath it to protect the frame from wear. For maximum durability, the external fuel line is specifically routed to make it less exposed and susceptible to damage. Additionally, the protective cap for the fuel filter prevents dirt and water from entering the system and shields it from impact damage.

Ride Easier

• FRAME: With an optimized distribution of material around the steering head and upper shock mount, the frame delivers confidence-inspiring handling and assured stability when entering corners. To complement the overall look of the machine, the chromium molybdenum chassis is finished with a premium, metallic blue powder coating. The finishing touches are the frame protectors, which not only protect the paintwork, but also provide riders with additional grip, even in the toughest conditions.
• POLYAMIDE-REINFORCED ALUMINUM SUBFRAME: Made from 60% polyamide and 40% aluminum, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 3.9 lb (1.8 kg). The lower subframe spars and frame mounts are manufactured from cast aluminum for strength at the lowest possible weight. Injection-molded polyamide is used to construct the upper section of the subframe to enable specific flex characteristics.
• CNC MACHINED TRIPLE CLAMPS: Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps endure precisely calculated geometry for stability. Handlebar flex can be customized with the handlebar clamp, which offers two mounting options - rubber-damped for less vibration, or fixed for enhanced front-end feedback.

A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners.

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 and false neutrals, the function is only active from second gear upwards.
• TRACTION CONTROL: Traction Control on the FX 350 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.
• E-START: The FX 350 starts with the ease of pressing a button thanks to electric start. A lightweight Li-Ion 2.0 Ah battery is fitted, giving the convenience of electric starting while keeping overall weight to a minimum.
• ENGINE MANAGEMENT SYSTEM: The KEIHIN EMS is designed to be small, lightweight, and fast at processing data. It integrates traction control for perfect starts, selectable engine maps via the switch on the handlebar, as well as Launch Control.
• HOUR METER: The hour meter comes with an integrated fuel level indicator, which is visible on the FI status LED, and warns the rider when the fuel level is getting low.
• START / STOP SWITCH: The combined engine 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, but the removal of an additional stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.
