KTM continues to unveil its 2020 off-road models, with the latest being the Austrian manufacturer's two largest-displacement EXC-F dual-sport bikes—the 500 EXC-F and 350 EXC-F. The two motorcycles share several updates to the engine, suspension, and chassis.

The engine cases are 300 grams lighter than the previous models and move the crankshaft closer to the bike’s center of gravity for improved handling. The new Pankl six-speed transmission is made of forged raw material for increased durability, while a new lithium-ion battery is claimed to be stronger and weigh less for better starting and improved handling. The shorter and more compact exhaust system features a two-piece head pipe design for improved performance and easier mounting. The airbox is new and has an updated velocity stack, both of which are designed to provide better airflow and improved air filter protection.

The WP suspension components on both EXC-Fs have been updated as well. The Xplor fork features a new mid-valve piston for more consistent damping and new settings to keep the front end higher for better rider feedback and increased bottoming resistance. The fork also has new caps and adjusters. The Xplor shock has a new second piston and reworked sealing cup shape for improved bottoming resistance, while new settings are designed to offer improved comfort.

The 500 EXC-F and 350 EXC-F chassis feature a stiffer frame that is now black instead of orange, new bodywork, a 40mm longer subframe, new aluminum head stays, newly designed radiators that are mounted 12mm lower, a reworked wiring harness and packaging, a new fuel tank, a newly shaped seat, different cable routing of the throttle body, and updated graphics.

Model-specific changes to both bikes are engine related. The 500 EXC-F has a new cylinder head that is 500 grams lighter and 15mm shorter, a new camshaft, shorter valves, new rocker arms that have a stiffer design and reduced inertia, and a new port shape for improved gas flow. A new König piston with a 10 percent lighter piston pin helps increase the compression ratio from 11.7:1 to 12.75:1. The final update made to the 500 EXC-F is a new reinforced clutch cover for better durability.

The 350 EXC-F features a reworked cylinder head that is 200 grams lighter and has new flow-optimized ports, along with a new CP piston and shorter cylinder that together produce an increased compression ratio (from 12.3:1 to 13.5:1). A reworked crankshaft with a new small-end bearing for improved reliability rounds out the updates made to the 350 EXC-F for 2020.
