2021 KTM 500 XCF-W, 2021 KTM 500 XCF-W DYNAMIC AND POWERFUL

Stand back or hold on tight, this is the most powerful offroad bike on the market. The latest generation KTM 500 XCF-W packs a thrilling 4-stroke punch while still delivering outstanding rideability. Thanks to its lightweight chassis and compact high-tech engine, this large-displacement power machine is surprisingly light with excellent agility. As a result, this awesome 510 cc SOHC single cylinder bombshell has an incredible power-to-weight ratio and provides nothing less than the most dynamic offroad experience available.

ENGINE & EXHAUST

Power and torque

• ENGINE

Compact dimensions with an immense power output, the KTM 500 XCF-W’s fuel-injected SOHC engine is the most powerful and refined 500 cc on the market, thanks to newly developed camshafts, exhaust system and updated electronic fuel injection. Its class-leading power delivery is available throughout the entire rev range and with its small dimensions and low weight, this engine is compact, light and the most competitive powerplant out there.

• CYLINDER HEAD

The 500 XCF-W engine is fitted with a newly developed SOHC cylinder head which is much more compact, 15 mm lower and 500 gr lighter improving the mass centralization and contributing to even better handling. The gas flow through the newly shaped ports is controlled by a new overhead camshaft which is now closer to the center of gravity for improved handling. It features a better axial fixation of the de-compressor shaft and a new, more efficient integrated engine breather system. The four new valves are shorter and adapted to the new head design, but retain the same valve timing as the predecessor. The rocker arms have been optimized with a stiffer design, guaranteeing more constant performance throughout the rpm range. A shorter timing chain and new low-friction chain guides contribute to the engine’s overall reduced weight and lower friction. The new head configuration promises more efficient power delivery and unrivalled performance.

CHASSIS

• FRAME

All XCF-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 redesigning certain areas they now have a higher lateral, longitudinal and torsional stiffness, 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
