Ride Easier

• FRAME: For 2025, new engine mounts with cut-outs improve the chassis flex characteristics, reduce weight, and contribute to a confidence inspiring riding experience. The frame is revised by reducing and removing material around the steering head and shock mount, which lowers the weight of the frame by 300 g. Together, these revisions improve cornering and ensure unparalleled rider feedback, energy absorption, and straight-line stability. A premium metallic blue powder coating is applied to the frame with protectors offering superior protection, durability, and grip in all 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.
• TRIPLE CLAMPS: Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for increased 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. The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.

For 2025, the settings are updated to suit the new frame and linkage revisions. Inside the forks, mid-valve pistons optimize oil flow and prevent foaming for consistent and predictable damping at all times. A hydrostop, active in the final 68 mm of travel, reduces the impact of harsh and high-speed landings for continued straight line stability and forward momentum. Both the compression and rebound settings can be quickly adjusted by hand using the easy access clickers.
• WP XACT REAR SUSPENSION: Inside the WP XACT rear shock is a Computational Fluid Dynamics (CFD) optimized main piston for superior initial comfort and to provide strong hold-up in all conditions. Updated for 2025, the linkage features new, lower friction seals while a smaller diameter linkage bolt reduces weight. The standard rebound and high and low speed compression settings have been adapted to suit the new frame and can be easily adjusted by hand to create a personalized set-up.
• SWINGARM: The swingarm is manufactured using a die-cast production process for optimal rigidity. To optimize and match the flex characteristics of the chassis, a 22 mm rear axle is utilized. For 2025, the machining of the swingarm helps to improve the durability of the new chain slider.

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.
• QUICKSHIFT: 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.
• 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.
• 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.
