KTM 500 EXC-F
KTM 500 EXC-F (XCF-W) is the most powerful bike in the KTM Enduro range.
This motorcycle combines a high-tech four-stroke engine with a lightweight chassis for excellent maneuverability. Basically, this is an EXC 450 with a modified piston stroke to achieve a larger engine displacement.
Small, high power: The KTM 500 EXC-F fuel injection powerplant is the smallest and lightest 500cc engine on the market, while delivering torque and power across the entire range. The newly redesigned four SOHC cylinder head valves are controlled by extremely rigid rocker arms. Optimized ports provide efficient gas exchange, and a sophisticated water jacket ensures reliable heat dissipation. The piston crown geometry is ideally matched to the highly efficient combustion chamber, while its low weight and high stiffness help to minimize vibration and improve reliability. Vibrations are also damped by a carefully optimized crank drive with sleeve bearings and a multifunctional balancer shaft. The Keihin electronic fuel injection engine management system with 42mm throttle body provides amazing throttle response with a unique injector position, while an optional map select switch allows the rider to select different engine characteristics and activate unique traction control for a better start.
The transmission has 6 gears, reinforced gears and is equipped with a gear position sensor, traction control system. In 2020, transmission has received a new, larger C4 bearing, which will provide increased reliability under extreme loads. The sprocket is injection-molded with a highly elastic surface and increased reliability.
The KTM EXC clutch (thanks to the Brembo hydraulic system and the DDS system) allows for fine metering of traction in difficult conditions, especially when driving in the hard-enduro class, the compactness of the DDS system allowed KTM engineers to install a damping system for additional reliability.
