2018 KTM 125 XC-W Enduro Bike – Features

2018 KTM 125 XC-W Enduro Bike


The new 2018 KTM 125 XC-W Enduro Bike features the most powerful and most competitive engine giving the best power. This 125cc engine is been developed with the KTM engineers with the most advanced technology. The use of new technology provides the best torque across the entire rev range while the engine is extremely compact and light. This engine uses the compact cylinder with the bore of 54mm containing the cutting-edge power valve unit with the latest mechanism for the lateral support exhaust ports. This twin-components cylinder head gives the best performance.

The layout of the new water jackets in the cylinder and head guarantees an efficient heat dissipation. The cylinder, head and piston unit of 150cc can also be fitted in it converting it to the 150cc without replacing the crankshaft. The new lightweight lateral brackets allows an efficient fixation of the engine. The engineers of KTM has developed the lightweight die-cast crankcase containing the high crankshaft position located close to the center of gravity. This relocation results in optimal mass centralization and excellent rideability.

The use of reliable piece of engineering ensure the minimal vibration. It allows an increases in the displacement of 144cc only by replacing cylinder, piston and head. The engine delivers the best performance like in 2017 KTM 125 XC-W Enduro Bike. This latest enduro bike is fitted with the new Mikuni TMX carburetor. The flat slide carb 38mm carb provides the smooth and controllable power all the way up of the rev limitation. The carburetor is turned about 7-degree to reduce the overflow of fuel plus it is less sensitive to different altitudes and temperature.

2018 KTM 125 XC-W Enduro Bike Engine

The wide-ratio of 6-speed Enduro transmission was designed for small 2-stroke Enduro engine. The modern production technologies allows for compact dimensions and minimal weight. There is an all-new ‘No Dirt’ gear shift lever design prevents the muck from blocking the joint. The clutch is activated by the hydraulic system make by the Brembo. This reliable and self-adjusting unit guarantees the light operation and highly controllable modulation.

The engineers have tuned the pipes of exhaust system for more power plus this little screamer is as tough as it is strong. All of the 2-stroke models comes with the new CDI control unit with an advanced hardware. It improves the starting behavior of the engine. Its ignition curves remain unchanged. The use of state-of-the-art cylinder layout and reliable piston provides an outstanding performance. The engine design allows the option of the customer to fit an E-starter. The KTM PowerParts kit includes all such hardware, which are needed to convert the bike. This starter gives an easy staring experience although it may cause an increase in the overall weight.

The new 2018 KTM 125 XC-W Enduro Bike features the lightweight and slimmest chassis of all times. The new high-tech and lightweight chrome-moly steel frame for an easy handling, precise cornering and ultimate stability. This bike also has high torsional rigidity and low longitudinal stiffness like the new 2018 KTM 125 SX. It results in the better absorption of the energy and smooth ride with its front and rear suspension. It ensure the more comfort and less rider fatigue.

The lightweight engine head are laterally attached which contribute to the reduction of vibration level. The new two threaded inserts in the lower cradle tubes allowing for safe fixation of an optional skid plate. The KTM engineers makes this bike a kilogram lighter than others. This bike is easier to maintain and has more space for the tank and other components. The subframe is made up of stable aluminum profile. The new ‘No Dirt’ footpegs prevent the dirt to stick in the pegs. The pegs on the Enduro models are about 6mm higher than the ones used on SX versions.

The design of swingarm allows for an optimized mounting position of its PDS shock absorber offering more progressive action. The new cast aluminum design ensure the low weight and perfect flex behavior. The new single-component casting process also eliminates all the inconsistencies and inherent weak points created during welding. The rear shock absorber is directly connected to the upper side of the swingarm. This setup provides incredible progressive damping and has awesome mounting geometry. This shock absorber is mounted much closure to the centerline, which means more space for an exhaust system. The second piston works together with the closed cup towards the end of the stroke and it is supported by the progressive shock spring for outstanding bottoming resistance. The color of WP trim makes it much valuable and high-end product as compare to the less refined shock absorber.

The WP Xplor 48 upside-down fork is the split fork developed by the WP in close association with KTM. It is fitted with the spring on its both sides featuring separated functions for each fork leg. The compression damping is fitted on its left side while the rebound is on the right. The forks can easily be adjusted for compression and rebound with the twist of the dial on the top of the forks. Its outer fork tubes and the reworked settings is best for more sensitivity, better damping behavior and low weight. The new sealed hydro-stop guarantees an excellent resistance to bottoming-out.

The new WP Xplor 48 fork features the travel of 300mm for best response and damping characteristics. The comfortable preload adjuster allows the simple spring preload setting in three steps without any use of tools. The new 2018 KTM 125 XC-W Enduro Bike features the forged triple clamps with an offsets of 22mm. It ensure the better solid grip of the fork and precise handling. Its handlebar is fully adjustable in four different positions. The brakes provide the best stopping force. It features the high-tech Brembo calipers with the lightweight Wave brake discs. The steel-flex front brake hose features an efficient protection.

The handlebars are made up of high-strength aluminum NEKEN featuring the throttle assembly with the robust aluminum body and easy adjustable. The ODI volcanized grip sits on the right while the left side of the bar are comfortable ODI lock-on grip.


The new 2018 KTM 125 XC-W Enduro Bike features the air filter design for maximum protection of air filter against soiling while it also ensures maximum airflow in a quiet way. The large Twin Air filter is mounted in the stiff cage and its design is so simple that one can easily pop a fresh one without any use of tools. The lightweight polyethylene tank is being used featuring the capacity of 10 liters.

The wheels are lightweight containing CNC machined hubs and high-end Giant rims ensuring the maximum stability at minimum weight. The wheels come with the Maxxis tires. The KTM‘s proven cooling system routes its coolant from the cylinder head through the frame triangle, directly to its aluminum radiators made by WP. This system is very efficient due to optimized internal circulation and CFD-calculated ventilation. The new radiator protection improves the heat dissipation, it is integrated into the front part of shrouds to protect the radiators in the crash.
