KTM 500 EXC-F SIX DAYS

Considered the hardest-hitting missile in the KTM enduro arsenal, the KTM 500 EXC-F SIX DAYS represents everything we love about big single-cylinder 4-stroke - torque, acceleration, and uncontestable power. Wrapped in all-new France Six Days Enduro (ISDE) edition colors, and featuring an extended list of top-of-the-line components, the KTM 500 EXC-F SIX DAYS brings the firepower.

ENGINE

Combining compact dimensions with immense power output, this 510 cc fuel-injected SOHC powerplant is the most powerful and refined on the market. Its class-leading power delivery is available throughout the entire rev range and with its low weight of only 29.2 kilograms, is also the lightest half-liter engine out there.

CYLINDER HEAD

The KTM 500 EXC-F SIX DAYS engine is fitted with a compact SOHC cylinder head for optimal mass centralization. The head configuration promises efficient power delivery and unrivaled performance. A single overhead camshaft also ensures optimal gas flow, with low-friction rocker arms and timing chain guides guarantee consistent performance throughout the rpm range.

CRANKSHAFT

Located in an ideal position close to the center of gravity, The KTM 500 EXC-F SIX DAYS' crankshaft contributes to easier handling. It utilizes a short connecting rod, which makes for an overall compact and lightweight engine. The engine's pressurized lubrication system provides the necessary oil feed for the big end bearing. This design has a direct benefit for the crankshaft with extended service intervals. So just pin it, all day long.

CRANKCASES AND ENGINE COVERS

A lightweight engine case design allows for a very centralized shaft configuration while contributing to an efficient centralization of mass. Additionally, the engine covers feature a smart surface structure that reduces the wear caused by the rider's boots, keeping them looking as fresh as the day it rolled off the production line, while a reinforced clutch cover and engine guard mean the engine case is more robust.

TRANSMISSION

The KTM 500 EXC-F SIX DAYS features a robust 6-speed transmission made by PANKL Racing Systems. The gears are made of a strong, forged raw material, ensuring the highest durability and reliability level. All four-stroke engines are fitted with a gear sensor, giving the option of different engine characteristics for each gear.

ENGINE MANAGEMENT SYSTEM

The state-of-the-art Keihin Engine Management System, with electronic fuel injection, features a 42 mm throttle body with separate systems for cold starting and idle adjustment. The throttle cable mount also allows for easy access and a smooth routing of cables for crisp throttle response, every time.

CYLINDER AND PISTON

Inside the short 95 mm bore cylinder is an extremely lightweight, box-in-box type piston made by König. In conjunction with the light but extremely durable piston pin, it is a major contributor to the engine's high performance, low vibrations, and speed. The compression ratio of 12.75:1 delivers exceptional engine performance and reduces the risk of engine knocking. Additionally, the top of the piston is optimized for highly efficient fuel combustion.

BALANCER SHAFT

The multifunctional side-mounted counter balance shaft masterfully balances all the oscillating forces, while also driving the water pump. It effectively keeps engine vibrations to a minimum, resulting in the smoothest ride even at the highest engine speeds.

CLUTCH

The KTM 500 EXC-F is fitted with the extremely durable, KTM-developed DDS clutch (damped diaphragm steel), with a wear-free steel basket and heat-resistant clutch plates. It uses a diaphragm spring instead of the usual coil springs, which results in considerably easier clutch action. Additionally, the Brembo hydraulic system provides easy and precise clutch modulation throughout the entire operating temperature range.

E-STARTER

The standard electric starter on the KTM 500 EXC-F SIX DAYS uses a proven starter drive and a strong starter motor made by Mitsuba. As demonstrated time and time again, it provides quick and reliable starting, saving you precious time and energy when you need it most.

COOLING

Keeping the engine cool when the going gets tough comes courtesy of a pair of radiators, mounted close to the center of gravity. These make use of CFD technology (Computational Fluid Dynamics) and clever coolant circuit routing, achieving optimum engine temperature for the highest performance, in all conditions. Above all, the delta distributor, integrated into the frame triangle, features a large center tube for highly efficient coolant flow, as well as radiator fans as standard on all 4-stroke models.

EXHAUST

Packing a punch and delivering an unmistakable engine note, all 4-stroke KTM SIX DAYS models feature an easy-access two-piece header pipe that can be disassembled easily to allow access to the rear shock. An aluminum muffler sleeve has a short and compact profile, which also proudly displays the SIX DAYS logo.

FRAME

All KTM SIX DAY models feature high-tech, lightweight Chromoly steel frames with race-derived geometry, optimal stiffness, and unparalleled feedback for the rider. This translates into a playful handling character, with remarkable stability at speed - not to mention FACTORY RACING style thanks to the striking orange coating. The subframe is made of extra-light and ultra-stable aluminum profiles, weighing less than 900 grams providing rear fender stability and durability in the event of a loop out.

SWINGARM

The KTM 500 EXC-F SIX DAYS features a one-piece aluminum swingarm, which is manufactured using a gravity die-cast production process. This results in exceptional strength at the lowest possible weight and the perfect flex behavior.

WHEELS

KTM uses lightweight, CNC-machined hubs and high-end GIANT rims on all KTM SIX DAYS models. These guarantee maximum stability and the bare minimum weight, while aluminum spoke nipples feature an innovative design, which reduces the need to continuously tighten the spokes. They also look the part with unique SIX DAYS branding.

TIRES

Putting the power to the ground is a set of aptly named, Metzeler 6 DAYS EXTREME tires. These provide excellent grip across any terrain, as well as self-cleaning knobblies to ensure all the traction, all of the time.

SUSPENSION

For 2023, all KTM EXC SIX DAYS models feature top-shelf WP suspension systems, focused on providing all riders of all levels with unmatched performance and consistency across all terrain types.

FRONT SUSPENSION

Leading the way in enduro-focused suspension, these adjustable 48 mm diameter WP XPLOR upside-down forks provide unmatched performance from both expert and amateur riders alike. Adjustability also comes easily, with compression damping dialed in on the left fork, with rebound on the right.

REAR SUSPENSION

The race-proven and fully adjustable WP XPLOR shock absorber features conical bushings between the pistons that allow for reduced suspension fade and wear. And, not only this PDS rear suspension design the of choice of champions in the quest for podiums, but it also leads the way when it comes to providing maximum traction for the rear wheel.

TRIPLE CLAMP
