E-STARTER

The KTM 250 EXC-F is fitted with a unique E-starter as standard, which is a clear advantage when it comes to crunch time in the heat of battle. A strong starter motor made by Mitsuba will fire time and time again at the push of a button. Even under extreme conditions, thanks to its more […]

CYLINDER HEAD

The centerpiece of the compact DOHC engine is this cutting-edge cylinder head. It features light, dual overhead camshafts with friction-optimized cam followers boasting a hard DLC coating. Four lightweight titanium valves and high-flow ports maximize the flow rate for an optimal power band and outstanding performance across the seemingly endless rev range of 12,800rpm. Two […]

CYLINDER AND PISTON

Inside the cylinder, with a bore of 78mm, thumps a reliable box-type piston made by CP. Its crown geometry is adapted perfectly to the high-compression combustion chamber (12.8:1), where its rigid structure and low weight maximize performance. Thanks to low oscillating masses, the engine revs freely with plenty of power.

CRANKSHAFT

The KTM 250 EXC-F’s crankshaft utilizes a short connecting rod, making 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. This design is a must for the extremely high engine speeds and the unrivaled power […]

CRANKCASES AND ENGINE COVERS

The design of the die-cast engine crankcases allows for a centralized shaft configuration, moving the crankshaft close to the bike’s center of gravity. All hail mass-centralization! The engine covers feature an advanced surface structure to reduce the wear caused by the rider’s boots.

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 250 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 engine uses a multifunctional balancer shaft that also drives the water pump and timing chain.

Chassi

Chassi

The 250 EXC-F shares the same race-winning chassis setup as the rest of the EXC-F range. WP suspension keep the wheels planted, while lightweight engineering and performance-orientated materials ensure riders and racers are equipped to perform on both the trail or race course.

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 lightweight polyethylene tank has a capacity of 8.5 liters. You will always be able to see how much fuel remains at a glance, thanks to the see-through plastic. By pushing the orange release button in the center of the fuel tank cap, the bayonet mechanism makes refueling quick and easy. It is fitted with […]

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 […]

Ergonomi og komfort

READY TO RACE ergonomics come standard on all KTM enduro machines. The 250 EXC-F is no different, making for an easy-to-ride, yet competitive enduro weapon.

HANDLEBAR

KTM engineers know how to handle handlebars. This tapered unit, made of high-strength aluminum by NEKEN, features a throttle assembly with a robust aluminum body and easy free-play adjustment. 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

The plastics on the entire EXC-F range have been crafted with one goal in mind: complete harmony between rider and bike. I-beam structures of the front and rear fenders guarantee maximum stability at speed, while maintaining a lightweight construction. They also stay cleaner for longer, while the unique brake hose routing on the front number plate prevents wear and tear.

DECALS
