2021 KTM 500 EXC-FDYNAMIC AND POWERFUL

Stand back or hold on tight, this is the most powerful offroad competition bike on the market. The latest generation KTM 500 EXC-F 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 cm SOHC single cylinder bombshell has an incredible power-to-weight ratio and provides nothing less than the most dynamic enduro experience available.

Features may include:

ENGINE & EXHAUST

Power and torque

• ENGINE

Combining compact dimension with an immense power output, the KTM 500 EXC-Fs fuel-injected SOHC engine is the most powerful and refined 500 cc on the market. Its class-leading power delivery is available throughout the entire rev range and with its low weight of only 29.2 kg, this engine is the most compact, lightest and most competitive powerplant out there. With Euro IV homologation, its not only considerately green, but leaves the competition green with envy too.

• CYLINDER HEAD

The KTM 500 EXC-F engine is fitted with a compact SOHC cylinder head for optimal mass centralization while contributing to even better handling. The head configuration promises efficient power delivery and unrivalled performance as the gas flow through the ports is controlled by a single overhead camshaft. It features a durable axial fixation of the de-compressor shaft and an efficient, integrated engine breather system. The rocker arms and low-friction timing chain guides guarantee a consistent performance throughout the rpm range.

CHASSIS

• FRAME

All EXC 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 side. The subframe is made of extra-light and stable aluminum profiles, weighing less than 2 lbs (900 gr) and is 40 mm longer than before, providing better rear fender stability.

• SWINGARM

The KTM 500 EXC-Fs one-piece aluminum swingarm is manufactured using a gravity die-cast production process, offering exceptional strength at the lowest possible weight. The single-component casting process offers low weight, perfect flex behavior and also allows for a large number of geometry solutions.

ERGONOMICS & COMFORT

Shaped for control

• HANDLEBAR

All KTM EXC models are equipped with the same high-strength aluminum tapered NEKEN handlebar. The handlebar allows for four different positions. The handlebars come standard with an ODI vulcanized grip on the right side and a comfortable ODI lock-on grip, which does not require any wire or glue, on the left.

Innovatively strong

• FOOTPEGS

Sophisticated No-Dirt footpegs prevent clogging up the pegs, even when digging in deep ruts. The pegs on the Enduro models are 6 mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.
