Engine

The FX 350 engine is designed to deliver maximum performance with all major engine components and shaft arrangements positioned to enhance overall handling. Weighing just 59.9 lb (27.2 kg), the 350 cc 4-stroke engine centralizes mass and aids the anti-squat behavior of the whole chassis.

Cylinder head

The DOHC cylinder head offers improved durability and serviceability, with diamond-like carbon (DLC) coated finger followers to guarantee minimal friction and optimal performance. These actuate large titanium valves, 36.3 mm for the intake and 29.1 mm for the exhaust, which optimize gas flow for strong, usable power across the rev-range, all the way up to the 13,400 rpm limit. Valve timings work in perfect harmony with the camshaft, which features a bearing bridge design for stiffness and easy serviceability.

Crankcases

Designed for optimized mass centralization, the FX 350 crankcases house all internal components in the perfect position to achieve the ideal center of gravity. Manufactured using a high-pressure die cast production process, the result is a thin, exceptionally strong wall thickness at the lowest possible weight.

Crankshaft

At the heart of the high-output, high-revving FX 350 engine is the crankshaft. This features a plain big end bearing rotating on two force-fitted bearing shells for maximum reliability and guarantees long service intervals of 90 hours.

Cylinder and piston

An 88 mm bore and 57.5 mm stroke cylinder is professionally engineered from high-strength aluminum for maximum reliability and houses the high performance forged bridged-box-type piston from CP. The compression ratio is 14.6:1 for exceptional torque and peak power.

DS clutch

The FX 350 features a diaphragm steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the clutch basket allows the use of thin steel liners that contribute to the compact design of the engine.

Gearbox

The 6-speed gearbox is manufactured exclusively by Pankl Racing Systems to ensure high durability and reliability. The shift drum and fork are designed for optimal leverage, ensuring smooth and precise gear changes in both upshifts and downshifts.

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 aluminium 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. 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.

WP XACT front suspension

Rigorously tested by the WP research and development department, the 48 mm WP XACT Closed Cartridge spring forks fitted to the FX 350 provide exceptional comfort. 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 to maintain forward momentum. Both the compression and rebound settings can be quickly adjusted by hand using the easy access clickers found on top of each fork leg.

WP XACT rear suspension

The WP XACT rear shock features a Computational Fluid Dynamics (CFD) optimized main piston, ensuring superior initial comfort and predictable performance in all conditions. To give riders the option of creating a personalized set-up, rebound, as well as the high and low-speed compression settings, can all be adjusted easily by hand.

Swingarm

The swingarm is manufactured using a die-cast production process and designed with a calculated level of rigidity. To further complement and optimize the flex characteristics of the chassis, a 22 mm rear wheel axle is utilized. A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners.

effortless ergonomics

Bodywork

The ergonomic bodywork was designed to ensure that riders can perform at their best throughout every race. This was achieved through extensive testing, with the smooth contact points in the rider triangle allowing racers to grip the machine tightly with their legs, reducing fatigue. The radiator shrouds, featuring in-mold graphics, contribute to the progressive appearance of the machine, while a tall, wide seat offers unrestricted movement. A high-grip seat cover also helps keep riders securely in place under hard acceleration.

Tool-less airbox

A strong, one-piece airbox optimizes air intake by reducing deformation. This design provides an unrestricted flow of air for maximum power, without compromising filter protection. The Twin Air filter can be easily inspected without tools by simply removing the left side panel.

Hydraulic clutch

The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. With this hydraulic system, free play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race-focused testing have proven the exceptional reliability of the high-quality, Italian-made Brembo hydraulic system.

Hydraulic brakes

Class-leading Brembo brake calipers, made from single pieces of aluminum for strength, are fitted front and rear to ensure high braking performance. Together with 260 mm front and 220 mm rear discs, both designed to prevent mud build-up, effective stopping power in all conditions is assured. The strong rear brake pedal is highly durable, and less susceptible to damage when riding through deep ruts.

Protaper handlebar

Developed between Husqvarna Motorcycles and leading handlebar manufacturer ProTaper, the exclusive bend offers superior comfort, class-leading strength, and fatigue resistance at the lowest possible weight.

ODI grips

ODI lock-on grips feature an innovative, integrated throttle mechanism and are installed without using glue. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalized throttle action.

Footrests

The CFD-designed footrests are extra wide to ensure better control of the machine while at the same time, they are less susceptible to catching on deep ruts and trackside barriers. This is achieved by a narrower mounting design in the frame layout, which also helps reduce overall weight.

Wheels and tyres

CNC-machined hubs, strong spokes, and high-strength, black-anodized alloy rims by D.I.D are used to assemble the wheels. They are fitted with versatile Dunlop AT82 tires. The front ensures precise cornering, while the rear provides excellent traction across varied terrain.

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 new 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.

Exhaust system

The exhaust system on the FX 350 features a flow-optimized resonance chamber, which plays a key role in delivering consistent performance. Manufactured in two pieces and designed for compactness, the header pipe allows the exhaust system to be removed without removing the rear shock.

technologically advanced

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.

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.
