£6,849.00



Model Description

'XC' means cross country. 'W' represents its wide-ratio transmission. 'KTM' stands for winning. This model is a race-ready bike built for closed course Enduro rides or races that don't require an homologated motorcycle. And for riders who don't want to drag around the extra weight that comes with homologation requirements. The KTM 125 XC-W simply is the lightest Enduro bike money can buy, while still being a heavyweight in terms of power. When the going gets tough, the tough get an XC-W.

ENGINE
The KTM 125 XC-W engine is the most powerful and most competitive engine in its class, providing precisely the kind of power an Enduro rider wants. This 125cc ripper has been developed with the latest KTM engineering know-how and the most advanced technology available. The results: whopping power and mountain conquering torque across the entire rev range, while being extremely compact and light.

CYLINDER AND CYLINDER HEAD
This compact cylinder with a 54mm bore features a cutting-edge power valve unit with a sophisticated mechanism for the lateral support exhaust ports. Matched to a twin-component cylinder head, it is KTM's secret to all-round grunt. The layout of the water jackets in the cylinder and head guarantees efficient heat dissipation when the going gets tough. A 150cc cylinder, head and piston unit can now also be fitted to this engine base, converting it to a 150 without replacing the crankshaft. And to top this power pack off, lightweight, lateral brackets allow an efficient fixation of the engine to the frame. What's not to like?
 
CRANKCASES
The KTM engineers designed lightweight die-cast crankcases featuring a high crankshaft position located close to the center of gravity, which results in optimal mass centralization and outstanding rideability.

CRANKSHAFT
This reliable piece of engineering has been skillfully balanced to guarantee minimal vibration. In its latest form, it allows an increase of the displacement to 144cc just by replacing cylinder, piston and head. There's no more need to change the crankshaft. Two-in-one in no time.

CARBURETOR
The KTM 125 XC-W is fitted with a MIKUNI TMX carburetor. This 38mm flat slide carb lives to provide smooth and controllable power all the way up to the rev limitation. With a new intake manifold the carburetor is turned 7° to reduce the overflow of fuel. And it's less sensitive to different altitudes and temperatures, so you can pin it wherever, whenever.

TRANSMISSION
A wide-ratio 6-speed Enduro transmission was designed specifically for the small 2-stroke Enduro engine, its gear ratios perfectly in sync with the 125's power band. The latest production technologies allowed for compact dimensions and minimal weight. Keeping safety in mind, an advanced ´No Dirt´ gear shift lever design prevents muck from blocking the joint. Because even dirt lovers hate mud when it's in the wrong places.

CLUTCH
The clutch is activated by a hydraulic system made by Brembo. This reliable and self-adjusting unit guarantees light operation and highly controllable modulation.

EXHAUST SYSTEM
The engineers meticulously tuned the pipe for maximum power, so this little screamer is as tough as it is strong.

IGNITION
All 2-stroke models feature a new CDI control unit with an advanced hardware which improves the starting behavior of the engine. The ignition curves remain unchanged.

PISTON
This little gem is optimized for maximal reliability and its shape fits brilliantly to the state-of-the-art cylinder layout.

E-STARTER
The design of the new 125cc engine allows the option to the customer to fit an E-starter. A KTM PowerParts kit includes all the hardware needed to convert the bike. Even though the overall weight rises slightly, there are clear benefits having the magic button, especially for the ones looking to compete on an extreme level.

FEATHERWEIGHT
KTM engineers just love shedding weight. The result: the current KTM XC-W's are the slimmest, lightest bikes in the Enduro scene.

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 and less rider fatigue. Laterally attached, lightweight engine head stays (the connection between cylinder head and frame) contribute to a reduced vibration level. Two threaded inserts in the lower cradle tubes allow for safe fixation of an optional skid plate. The engineers could pull off all that, while making their frame a big fat kilogram lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light subframe made of stable aluminum profiles, which tiptoes the scales at less than 900g.

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

SWINGARM
This design allows for an optimized mounting position of the PDS shock absorber, providing more progressive action. Furthermore, the cast aluminum design guarantees low weight and a perfect flex behavior. The single-component casting process also eliminates any inconsistencies and inherent weak points created by welding. And it's better looking.

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 more space for the exhaust system. A second piston works together with a closed cup (instead of a needle) towards the end of the stroke and is supported by a progressive shock spring for exceptional bottoming resistance. Various machined and anodized components and a distinctive WP color trim make this a valuable, high-end product compared to the less refined shock absorbers of the competition.

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 for compression and rebound with the twist of a dial on the top of the forks. New outer fork tubes and a reworked setting make for more sensitivity, improved damping behavior and a reduced weight. In addition, a sealed hydro-stop guarantees excellent resistance to bottoming-out. Due to high-quality materials and a state-of-the-art production process, the new WP Xplor 48 fork – with approx. 300mm of travel – has outstanding response and damping characteristics. A comfortable preload adjuster can be retrofitted and allows for a simple spring preload setting in three steps without tools (standard, +3mm, +6mm).

TRIPLE CLAMP
The XC-Ws 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 XC-W will fit you like your favorite gloves.

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.

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 to secure it.

AIR FILTER BOX
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 could still pop a fresh one in with a face full of mud. Without tools. In seconds.

FUEL TANK
A lightweight polyethylene tank with a capacity of 10 liters. You will always be able to see how much fuel there's left 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.

WHEELS
The KTM 125 XC-W wheels feature lightweight, CNC machined hubs and high-end Giant rims guaranteeing maximum stability at minimum weight. The wheels are fitted with the latest MAXXIS tires. Take them wherever you like, traction will be waiting.

COOLING SYSTEM
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, new radiator protections improve heat dissipation. Especially in the mud. They are also integrated into the front part of the shrouds to protect the radiators in a crash.

BODYWORK
KTM R&D, KISKA Design and the factory racers had their say in shaping the plastics with one goal: complete harmony between rider and bike. Perfect ergonomics and contact points provide maximum comfort in movement on the XC-W. The I-beam structures of the front and rear fenders guarantee maximum stability and a low weight thanks to well thought-out construction and mounting. They also stay cleaner for longer. Clever brake hose routing on the front number plate prevents wear and tear.
