2025 GAS GAS EC 450F

Enduro Anywhere

Heading off to explore an abandoned town? Done. Churning dirt in a forest? Easy. Charging through the deep sandy deserts? Let's go! The KTM 500 EXC-F doesn't shy away from anything. Churning out hp, and built around a lightweight frame with best-in-class suspension, this large-displacement powerhouse is surprisingly usable, making the KTM 500 EXC-F the ultimate half-liter weapon in anyone's Enduro arsenal.

Adjustability

Getting READY TO RACE has never been easier. The KTM Enduro range boasts a tool-free suspension setup at both ends. At the rear, our legendary, race-winning PDS technology features hand-adjustable dual compression controls, allowing riders to adjust high- and low-speed settings in a matter of seconds. On the front, the forks are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and on the fork top cap, making changing settings on the fly as easy as twisting the throttle.

Air Filter Box

The air filter box is designed to ensure maximum airflow with minimal water intrusion. Precision in how the inlet ducts are positioned is aimed at preventing air deformation and maintaining filter protection.

An enduro-specific splash protector under the airbox prevents water or dirt from splashing up from the rear wheel, while the Twin Air filter and air filter support design features a simple fail-proof mounting system for a secure and accurate filter installation. All this ensures the air filter is easily accessed, without tools, for fast trail-side maintenance.

Fuel Tank

The transparent, polythene (XPE) fuel tank is a signature element of the KTM Enduro lineup. Having undergone thorough race testing in everything from the GNCC to the hardest of FIM hard enduros, these tanks are built, well, like tanks! A one-piece fuel pump and filter manage fuel supply, while servicing is made extra simple with easy fuel filter access. What's more, an updated fuel tank roll now holds the tank more firmly in place and protects the frame against scrubbing:

Switchgear

On the right side of the handlebar, you'll find a new, sleeker start/stop switch that's taken directly from our motocross machines.

Graphics

The KTM Enduro Range gets a fresh color update. Orange dominates the color palate, but shades of dark purple and red make an appearance, creating a unique, but ultra-READY TO RACE look. As always, all graphics remain in place thanks to in-mold technology, while the seat features a high-grip seat cover in black, with the same texture shared across the frame protectors, tank spoilers, and the bar pad.

Engine

Warp speed engaged! The SOHC engine in the KTM 500 EXC-F is an undeniable powerhouse. Weighing in at a mere 65 lb (29.5 kg), it's remarkably lightweight for its power output. Designed with mass centralization in mind, this hard-hitting power factory features a low center of gravity, providing exceptional handling, maneuverability. and overall anti-squat behavior.

CPC Fuel Connector

A protection cap is used for the CPC fuel connector on all models. This not only prevents dirt from entering the sides of the connector and prevents mistakenly opening, but also adds protection from sticks or stones that might hit it. The small fuel filter in the fuel hose still stays in place and is easily accessible.

Cooling System

A radiator fan is fitted as standard equipment across the KTM EXC and EXC-F model range.

Offroad Control Unit

The Offroad Control Unit - or OCU - is located under the seat and replaces all the electronic fuses and relays. All outputs are switched depending on signals from the voltage regulator and the ECU continuously. In the event of over-current, outputs are deactivated individually. This makes for easy error detection as the status of each output is indicated by a red or green LED light. This means diagnosing an electrical issue out on the trail is as easy as lifting the seat, and there's no more need to carry fiddly fuses.

Battery & Wiring Harness

As with the rest of the KTM 4-stroke range, the KTM 500 EXC-F is fitted with a proven, reliable electric start system. Powered by an ultra lightweight 2 Ah lithium-ion starter battery, it provides reliable starting time and time again, while the wiring harness has most of the electrical components carefully positioned under the seat for easy accessibility.

Ergonomics

The KTM Enduro range features a rider-focussed body-position triangle, providing improved knee contact - especially when standing on the pegs - with improved gripping surfaces all around. With the plastics working to expel mud buildup in wet, muddy conditions, a flat seat profile with a high grip seat cover providing exceptional rider movement and control, and a polyamide-reinforced aluminum subframe providing unmatched rider feel and feedback, your only concern is navigating the terrain ahead of you.

Exhaust

The exhaust system is designed to deliver hard-hitting performance at the lowest possible weight and noise. The 2-piece header pipe design is made to be as compact as possible, with the routing of the header pipe extremely close to the engine for maximum of mass centralization and minimum exposure to rocks. A short, compact silencer is crafted from lightweight aluminum and finished in a premium matt black coating.

Frame

Specifically engineered for longitudinal rigidity, the KTM Enduro range is engineered around a black powder coated frame providing exceptional rider feedback, energy absorption, and high-speed stability. This is achieved by repositioning the rotating masses in the frame along with a forged steering head connection. The footrest mounts also feature a slim design for less risk of hooking up. And when the ride comes to an end, a forged one-piece side stand ensures your enduro weapon stands proud.

Subframe

An ultra-light lightweight subframe takes charge at the rear of the main frame, featuring a 2-part polyamide and reinforced aluminum construction. With the help of computational dynamics, a specific rigidity was engineered into the subframe, to deliver outstanding handling and rider feedback. This compact subframe design also boasts the the ability to bend and flex in the event of a crash, rather than break, with the subframe fully integrating electronic components, without any extra need for brackets, holders, or unnecessary fixtures.

WP XACT Closed-Cartidge Fork

The proven 48 mm WP XACT Closed Cartridge fork has been updated with shorter, lighter main springs with a polished surface, which improves durability and reduces weight by 200 grams. This means these forks ensure unmatched performance at every level. But, best of all, the fork allows for full adjustment of compression and rebound without the need for any tools.

WP XPLOR Shock

Remaining a hallmark of KTM Enduro weaponry, a PDS rear shock concept improves the anti-squat behaviors of the chassis. This remains the most reliable and maintenance-friendly option for competitive enduro racing. Moreover, a lightweight WP XPLOR PDS rear shock takes charge at the rear. For 2025 the rear shock received updated settings, resulting in improved pressure balance within the shock. With consistent damping, as well as full adjustability thanks to easy-to-use hand clickers for adjustments on the fly, it remains the setup to beat.

Wheels And Tires

The KTM 500 EXC-F rolls on a set of high-strength GIANT alloy wheels coupled to CNC-machined hubs and aluminum nipples. These are wrapped in a set of ultra-grippy Continental TKC 80 tires, providing exceptional traction in all conditions.

Stability

The KTM Enduro range remains rock-solid at any speed thanks to a repositioned and forged steering head connection and CNC-milled triple clamps. Made from high-grade aluminum, these feature optimally tuned steering stem stiffness, perfect alignment of the fork tubes, and precise geometry of the fork clamps to ensure highly responsive and smooth fork action - not to mention unwavering stability for those ultra-fast flat-out special stages.

LED Headlight

Lighting the way forward, the KTM Enduro range features an LED headlight unit and light mask. The mask itself features improved triple clamp protection against roost and does away with the rubber mounting straps for improved fitment. Most importantly, the LED lighting unit provides serious illumination, making riding in the dark a completely new experience.
