2022 KTM 250 XC-W TPI

The KTM 250 XC-W TPI is the ultimate combination of power and rideability and sets a clear benchmark for

intuitive handling, unique style and top performance. Thanks to its groundbreaking TPI technology, this

extreme machine continues to reach new heights, clearly demonstrating KTM's unrelenting commitment

to 2-stroke development. Besides the renowned benefits of excellent fuel efficiency, clean exhaust

emissions and the removed need for jetting, the KTM 250 XC-W TPI features a dynamic, lightweight frame.

It was developed with feedback from factory riders and in hindsight, returns the favor by offering excellent

rider feedback.

ENGINE & EXHAUST

Engine: The 250cc 2-stroke engine has plenty of power and torque but remains light enough for riders to

muscle their way through the toughest obstacles. Thanks to state-of-the-art engineering, innovative 2-

stroke design, and revolutionary TPI fuel injection technology, and a 13:52 re-gear, the powerplant is even

more refined than ever before. The compact and lightweight 2-stroke is a great choice for offroad riders

who want usable enduro performance that is ready to conquer in the most extreme terrain.

Cylinder: The cylinder on the KTM 250 XC-W TPI has a bore of 72 mm and is fitted with a sophisticated

power valve, providing ultra-smooth and controllable power characteristics. Being fuel-injected, the

cylinder features two lateral domes which hold the fuel injectors, supplying 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 for fewer emissions, more efficient combustion, and reduced fuel

consumption. The cylinder also features a state-of-the-art 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.

Crankcases And Engine Covers: These compact engine cases are manufactured using a high-pressure die

cast production process which helps with weight reduction but maintains strength and durability. This

design also allows for optimal shaft arrangements close to the center of gravity, resulting in ideal mass

centralization and ride-ability.

Transmission: The robust 6-speed transmission made by PANKL Racing Systems features an Enduro-

specific wide-ratio specification and provides precise and easy shifting. An advanced ´No Dirt´ gear shift

lever design prevents mud and dirt from blocking the joint. Because even dirt lovers hate mud when it's in

the wrong places.

Engine Management System: The engine management system (EMS) of all 2-stroke XC-W TPI models

features a control unit located below the seat. The ECU defines the ignition timing while the amount of fuel

to inject is based on several sensor readings such as intake air pressure, throttle position, water

temperature , and ambient air pressure. Thanks to altitude and temperature compensation, re-jetting is a

thing of the past, meaning more time twisting throttles and less time turning screws. Should the rider

decide to mount a radiator fan from the KTM PowerParts, it will be controlled directly by the EMS without

needing to add an additional thermal switch.

Balancer Shaft: The KTM 250 XC-W TPI engine design allows for the implementation of a lateral balancer

shaft in order to keep engine vibrations to a minimum. This means riders can focus on the obstacles ahead

of them, with out distraction. After all, more comfort equals less fatigue.

Clutch: The KTM 250 XC-W TPI employs the KTM-developed DDS clutch (damped diaphragm steel) with a

wear-free steel basket, extremely heat resistant clutch plates and nitrated steel liners. This
