Engine & Exhaust
Engine: The 250cc 2-stroke engine has plenty 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, 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: This compact cylinder with a 66.4 mm bore and with refined port timings and the aid of a sophisticated power valve, provides 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 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.
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. 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 TPI.
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 its in the wrong places.
Balancer Shaft: Say goodbye to numb feet and hands. This engine design allows the implementation of a lateral balancer shaft in order to keep the vibrations to a minimum. You know what that means: more comfort, less fatigue, more racing.
Clutch: The KTM 250 XC TPI employs the KTM-developed DDS clutch (damped diaphragm steel) with a robust steel basket, extremely heat resistant clutch plates and new, nitrated steel liners reducing the wear. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action. A diaphragm spring also leaves sufficient space for a damping system to be integrated into the clutch hub. The goal is traction, but durability is as well. Light operation and telepathic amounts of control are standard with this hydraulic Brembo actuated clutch.
