Engine & Exhaust
Engine: Thanks to state-of-the-art engineering, innovative 2-stroke design and revolutionary TPI fuel injection technology, the 150 cc 2-stroke powerplant is more refined than ever before, delivering class-leading power throughout the entire rev range. The benefit to this compact, lightweight 2-stroke, is reflected in the highly effective power delivery and easy rideability, making it a great option for those looking to delve into more extreme action.
Cylinder: The KTM 150 XC-W TPI cylinder has a bore of 58 mm and with refined port timings and the aid of a sophisticated power valve, provides really smooth and controllable power characteristics. For the EFI application the cylinder features two lateral domes which hold the fuel injectors that supply fuel to the rear transfer ports. The downstream injection guarantees excellent atomization of the fuel with the upstreaming air. Thus, the loss of unburnt fuel is minimal, resulting in less emissions, a more efficient combustion and reduced fuel consumption. A small tube in the back of the cylinder is connected with an intake pressure sensor, which supplies pressure data to the control unit. The cylinder features a power valve unit with a sophisticated mechanism for the lateral support exhaust ports. The exhaust port layout increases engine performance, while the upper contour of the exhaust port has been machined to ensure more accurate port timing. The new cylinder, with TPI technology, produces outstanding performance over the entire range with significantly increased torque compared to its predecessor. Last but not least, the new cylinder allows for the use of a more widely available traditional type of spark plug.
Crankcases And Engine Covers: The compact engine cases are manufactured using a high pressure die-cast production process which helps with weight reduction, while retaining strength and durability. The design allows for optimal shaft arrangements close to the center of gravity, resulting in ideal mass centralization and easier ride-ability. To accommodate the larger alternator, the 2020 model has a new ignition cover. The engine covers feature a smart surface structure which reduces wear caused by the riders boots, keeping them looking as fresh as the day you bought your XC-W.
Transmission: The KTM 150 XC-W TPI is now fitted with a robust 6-speed transmission made by PANKL RACING SYSTEMS. The gear ratios were carried over from the predecessor, but all the gears feature improvements and reinforcements. Instead of using a circlip for the pinion, the secondary drive is now fixed and secured with a screw and diaphragm spring as on all other offroad models. This guarantees superior reliability. Another highlight of the KTM 150 XC-W TPI transmission, is the no-dirt gear shifter. Similar to the footpeg design, it prevents the build-up of dirt and ensures the next gear is always available, no matter what the conditions.
Clutch: The 150 XC-W TPI is fitted with a DS (diaphragm steel) clutch. It features a one-piece clutch basket and primary gear made of high-strength billet steel. Its compact rivet-less design guarantees unbeatable reliability. The clutch is fitted with extremely heat-resistant steel carrier friction discs which ensure excellent disengagement of the clutch and are pre-tensioned by means of a diaphragm spring, substantially reducing the lever force required by the Brembo hydraulic system.
