2021 KTM 300 XC TPI, NYS On Road Title

2021 KTM 300 XC TPI UNRIVALED POWER-TO-WEIGHT RATIO

Take the unrelenting ferocity of an SX bike, add a few extra horsepower and torque, a longer-range fuel tank and an 18" rear wheel to accommodate more rubber, and you're well-armed to dominate the dirt. In a nutshell, the KTM 300 XC TPI is arguably the most accomplished cross-country racer available.

ENGINE & EXHAUST

• 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 TPI cylinder has a bore of 72mm and is fitted with a state-of-the-art power valve, which provides really smooth and controllable power characteristics. For the EFI application the cylinder features two lateral domes that hold the fuel injectors supplying fuel into 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, 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.

CHASSIS

• FRAME

The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on precisely calculated stiffness of the frame. This results in better absorption of the energy created from the front and rear suspension, sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight aluminum engine head stays (the connection between cylinder head and frame) contribute to more precise cornering and a reduced vibration level. The engineers were able to pull off all that, while making their frame 2.2 pounds lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light subframe made of aluminum, which tips the scales at less than 2 pounds.

• SWINGARM

The cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It's better looking too.
