2021 KTM 300 XC-W TPI

2021 KTM 300 XC-W TPIMASTER OF EXTREMESThe KTM 300 XC-W TPI has been at the forefront of the insane pace of development of the highest levels the sport of Extreme Enduro. This nimble, lightweight all-terrain master fears no obstacle and with the advent of TPI technology, has risen to ridiculous new heights. The refined bodywork and ergonomics make moving around a bliss, while the frame allows the rider to select a line with instant precision. An innovative and strong 3D stamped exhaust, as well as the impressive cooling and suspension, all help to make the new KTM 300 EXC TPI ready for the most extreme enduro challenges.
Features may include:

Light and powerful

• ENGINE

The 300 cc 2-stroke engine is known and respected for offering the most powerful 2-stroke performance in its segment. Thanks to state-of-the-art engineering, innovative 2-stroke design and revolutionary TPI fuel injection technology, the powerplant is more refined than ever before. The compact and lightweight 2-stroke is a great choice for all Enduro riders searching for easy-to-ride Enduro performance with the power and torque to conquer the most extreme climbs.

• CYLINDER

The KTM 300 XC-W TPI cylinder has a bore of 78 mm and is fitted with a sophisticated power valve, which 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 for less emissions, a more efficient combustion and reduced fuel consumption. A little tube in the back of the cylinder is connected with an intake pressure sensor, which supplies pressure data to the control unit. As of the 2020 model, the cylinders feature an improved power valve unit with a sophisticated mechanism for the lateral support exhaust ports. The new exhaust port layout increases engine performance, while the upper contour of the exhaust port has been machined to ensure more accurate port timing. Last but not least the new models allow the use of a more widely available type of traditional spark plug.

Optimal control

• FRAME

All XC-W models feature new high-tech, lightweight chromoly steel frames. This includes hydro-formed elements produced by state-of-the-art robot welding. They retain their race-proven geometries, but by re-designing certain areas, the stiffness has been optimized, resulting in better feedback for the rider, playful handling and improved stability. The laterally attached engine head stays (the connection between cylinder, head and frame) are now made of aluminum, reducing vibration and further contributing to precise cornering. The bikes also feature newly designed lateral frame guards with a structured surface, improving grip, while also serving as a heat protector against the muffler on the right side. On the KTM 300 XC-W TPI frame, the engine is lowered by 1 around the swing arm pivot improving front wheel traction significantly. The subframe is made of extra-light and stable aluminum profiles, weighing less than 900g and is 40 mm longer than before, providing better rear fender stability.
