These 38 mm flat slide cards provide the smooth and controllable power all the way up to the limiter. The bike is less sensitive to different altitudes and temperature.

Chassis

The new 2017 KTM 125 XC-W bike is high-tech lightweight chrome-moly steel frame which has a knack for easy handling, outlandish rideability, accurate cornering and incredible stability. The new 2017 KTM 125 XC-W has a high rigidity of torsional and low longitudinal stiffness. It will result in better energy absorption which is created from the rear and front suspension by sucking up bumps and jumps. In other, this bike will provide more comfort and less rider fatigue. The bike has a laterally attached, lightweight engine head which contributes to a reduced vibration level.

The two threaded inserts in the lower cradle tubes which allow for safe fixation of an optional skid plate. The engineers were able to make their frame a big fat kilogram lighter than that of the lightest competitor on the market. The bike is easier to maintain, simpler to work on and supplies more space of the tank and other components. The bike also contains an extra light subframe made up of a stable aluminum profile. The design of the bike allows the optimized mounting position of the PDS shock, which provides more progressive action. Also, the design of the cast aluminum ensures the lower weight and a perfect flex behavior.

The new 2017 KTM 125 XC-W has a single-component casting process eliminates any inconsistencies and the inherent weak points created by welding. The new footpegs prevent from smudging up the pegs, even when digging in deep ruts. The pins on the EXC models are 6 mm higher than those which were used on SX versions, which benefits ground clearance. The KTM engineers have developed unusual handlebars. These are made up of high strength aluminum NEKEN which contains the newly formed throttle assembly with a robust aluminum body and are easy free play adjustment. The ODI vulcanized grip fits on the right, while on the left side of the bar, the comfortable ODI lock on the grip is installed, which do not require any wire or glue to be fixed.

The new 2017 KTM 125 XC-W has a perfect ergonomics, and it contains a contact point which maximizes the freedom movement, sweet comfort of a flat seat, especially in the rear part of a seat. The new 2017 KTM 125 XC-W has an I-beam structure of the rear and front fenders which are the best examples of intelligent design, ensures the maximum stability. The headlights are working correctly, and the braking system is incredible. The new 2017 KTM 125 XC-W has a tailor made kit, especially for champs.

Suspension and brakes

The new 2017 KTM 125 XC-W has a WP XPlor 48 upside down fork which is a split fork developed by WP in collaboration with KTM. Their forks are fitted with the spring on both sides, but it contains separated function for each fork leg. The compression damping is mounted on the left side, while the rebound is on the right. So these forks are easily adjustable for compression and rebound with the twist of a dial on the top of the fork tubes. Moreover, the bike has a longer and sealed hydro stop which ensure the better resistance to bottoming out.

The new XPlor 48 fork comes with a high-quality material and starts of the art production with approximately 300 mm of travel, which ensures the outstanding response and damping characteristics. The new 2017 KTM 125 XC-W has a new and optional preload adjuster which allows for a threefold spring preload setting without any help of tools.
