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.
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.
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.
The standard electric starter on the KTM 500 EXC-F 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.
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.
Packing a punch and delivering an unmistakable engine note, all 4-stroke KTM EXC models feature an easy-access two-piece header pipe that can be disassembled easily to allow access to the rear shock. An aluminium muffler sleeve has a short and compact profile.
All KTM EXC 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. The subframe is made of extra-light and ultra-stable aluminium profiles, weighing less than 900 grams providing rear fender stability and durability in the event of a loop out.
The KTM 500 EXC-F features a one-piece aluminium 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 behaviour.
KTM uses lightweight, CNC-machined hubs and high-end GIANT rims on all EXC models. These guarantee maximum stability and the bare minimum weight, while aluminium spoke nipples feature an innovative design, which reduces the need to continuously tighten the spokes.
New, race-specification, puncture-resistant MAXXIS MaxxEnduro are designed for all-day riding comfort, with extreme grip and performance across any terrain.
For 2022, all KTM EXC models have received a suspension update, with a firmer factory setting focusing on performance and improved consistency across different terrains.
New slots in the outer fork tube mean the 48 mm diameter WP XPLOR upside-down forks feed more oil to the bushes and reduce friction and heat build-up. The fork springs have also been updated with a new polished surface finish to improve consistency and new valve design increases rebound damping performance. The forks retain their adjustability, with compression damping on the left and rebound on the right.
The race-proven and fully adjustable WP XPLOR shock absorber has received a re-tune, with factory settings making it firmer, and new conical bushing between the pistons to improve bottoming reserves. This has resulted in reduced fade and improved wear, taking the PDS rear suspension design even further in its quest for podiums.
When it comes to bringing this machine to stop, you'll be happy to have high-tech Brembo brake calipers and lightweight wavy discs doing the business. These also take years of competitive racing into account, providing the perfect combination of ideal pad density and steel quality for longevity and consistent feel.
All KTM enduro models are fitted with lightweight polyethylene tank, with a ¼‐turn bayonet-style filler cap makes for quick and easy operation. The integrated fuel pump ensures a direct feed to the injectors, while a 90° connector provides protection against damage. The tank is also manufactured using see‐through plastic, riders are able to gauge fuel levels at a glance and on the go.
The easy-access airbox on the KTM 500 EXC-F ensures optimal flow dynamics, thanks to specially designed intake snorkels. This means air is force-fed into the motor, resulting in the perfect balance of power and throttle response. Keeping the air clean, is a large Twin-Air air filter fitted to a rigid cage for ideal placement at all times.
03. ERGONOMICS & COMFORT
All KTM EXC models are equipped with adjustable, high-strength aluminium tapered handlebars made by NEKEN. These can be mounted in four different positions. Standard with ODI vulcanized grip on the right side and a comfortable ODI lock-on grip on the left, your only worry is hanging on, and letting rip.
Go ahead, take a seat. The 2022 KTM 500 EXC-F's seat is perfectly shaped to allow riders complete freedom of movement, but comfortable enough to maintain longer sessions in the saddle, and is covered in a grippy factory-inspired seat blue vinyl.
Self-cleaning footpegs prevent mud from clogging up the pegs, even when dragging them through deep ruts. This means your boots maintain their grip, and you maintain your focus on the trail.
04. BODYWORK & GRAPHICS
Drawing inspiration from the RED BULL KTM FACTORY RACING TEAM, the 2022 KTM EXC range features a bold contrast of orange and blue tones, as well as a factory-inspired blue seat. These are applied using in-mold graphics, which feature greater friction and fade resistance, meaning your steed will look factory-fresh after even the toughest time spend on the trails.
05. SOFTWARE & ELECTRONICS
Battery & wiring harness
No one wants to kickstart a 510 cc behemoth. For that reason, the KTM 500 EXC-F is fitted with a time-proven electrical system, powered by a super lightweight 2 Ah lithium-ion starter battery.
