CYLINDER HEAD

A single overhead camshaft controls intake and exhaust through optimized ports, while a cutting-edge combustion chamber and water jacket create mind-blowing power while managing heat. The engine’s four valves rely on extremely rigid rocker arms. Double lateral brackets fix the engine to the frame and reduce vibrations.

CYLINDER AND PISTON

Inside the cylinder, with a bore of 95mm, thumps a forged box-type piston with an ultra-light piston pin. Its crown geometry is adapted perfectly to the combustion chamber, where its rigid structure and low weight shine. Thanks to low oscillating masses, the engine is as smooth as it’s powerful.

CRANKSHAFT

The KTM 500 EXC-F’s crankshaft utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine’s pressurized lubrication. […]

CRANKCASES AND ENGINE COVERS

The design of the die-cast crankcases allows for minimal weight and a very centralized shaft configuration. This makes the engine short and compact, while contributing to an efficient centralization of masses. The engine covers also feature a solid surface structure, which reduces the wear caused by the rider’s boots. This way, your EXC-F will keep […]

COOLING

KTM’s proven cooling system routes the coolant from the cylinder head through the frame triangle, directly to aluminum radiators made by WP. Thanks to flow optimized internal circulation and CFD-calculated ventilation, the system is superbly efficient. In addition, the radiator protectors improve heat dissipation. Especially in the mud. They are also integrated into the front […]

CLUTCH

The KTM 500 EXC-F employs the KTM-developed DDS clutch (damped diaphragm steel) with a wear-free steel basket and extremely heat resistant clutch plates and nitrated steel liners. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action. A diaphragm spring also leaves sufficient space for a […]

BALANCER SHAFT

To balance the mass forces, the KTM 500 EXC-F engine uses a multifunctional, side-mounted balancer shaft, which at the same time drives the water pump. It has been balanced to perfection, keeping vibration levels to a minimum, even while gunning it to the maximum.

Chassi

Chassi

For 2019, all KTM EXC-F models continue with their compact and lightweight approach. This now means the 500 EXC-F is not only the most powerful KTM dirt bike, but also the leanest, meanest 500 cc in its class.

WHEELS

The EXC-F’s wheels feature lightweight, CNC machined hubs and high-end Giant rims guaranteeing maximum stability at minimum weight. The wheels are fitted with MAXXIS tires – perfect for surefooted performance off-road and stability on-road.

TRIPLE CLAMP

The EXC-Fs are fitted with forged triple clamps with an offset of 22mm, ensuring a solid grip of the fork and precise handling. The handlebar is adjustable forwards and backwards over 4 positions, so the EXC-F will fit you like your favorite gloves.

SWINGARM

This state-of-the-art swingarm allows for an optimized mounting position of the PDS shock absorber, providing more progressive action. Furthermore, the cast aluminum design guarantees lower weight and a perfect flex behavior. The single-component casting process also eliminates any inconsistencies and weak points.

REAR SUSPENSION

The PDS is kind of a KTM trademark where the shock absorber is directly connected to the upper side of the swingarm. This setup boasts the best possible mounting geometry and provides amazingly progressive damping. The shock absorber is mounted close to the centerline, which means nearly symmetrical loads for the swingarm and frame and […]

FUEL TANK

The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow in a quiet way. The large Twin Air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple; you can pop a fresh one in […]

FRONT SUSPENSION

The WP XPlor 48 upside-down fork is a split fork developed by WP in close collaboration with KTM. It is fitted with a spring on both sides but features separated functions for each fork leg: compression damping is fitted on the left side, while rebound is on the right. The forks can easily be adjusted […]

FRAME

The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on high torsional rigidity and low longitudinal stiffness. This results in better absorption of the energy created from the front and rear suspension, sucking up jumps and bumps. In short: more comfort […]

BRAKES

You can’t brake any harder, better, faster or stronger. High-tech Brembo calipers are combined with lightweight Wave brake discs. The steel-flex front brake hose has efficient protection and there’s an integrated channel for the speedometer cable. First you outrun them, then you outbrake them.

AIRBOX

The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow in a quiet way. The large Twin Air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple; you can pop a fresh one in […]

An ODI volcanized grip sits on the right, while on the left side of the bar a comfortable ODI lock-on grip requires no glue or wire […]

FOOTPEGS

Sophisticated ´No Dirt´ footpegs prevent jamming up of the pegs, even when digging in deep ruts. The pegs on the EXC models are 6mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.

Bodywork og dekaler

Bodywork og dekaler

KTM R&D, KISKA Design and KTM factory racers have collaboratively shaped the plastics and decals on the 2019 KTM enduro range. The mandate was simple – create complete harmony between rider and bike, keep the weight down and ensure KTM’s READY TO RACE spirit is felt both on and off the bike.

DECALS
