The 2007 KTM 450 SX-F and 505 SX-F are premier factory-styled motocross competition motorcycles featuring single-cylinder four-stroke engines in 449cc and 505cc displacements respectively. The 450 SX-F produces approximately 55 horsepower from its lightweight DOHC single-cylinder engine with four titanium valves and finger-follower rocker arms for reduced reciprocating mass. The 505 SX-F features a longer stroke crankshaft producing significantly more torque for riders prioritizing pulling power over top-end revs. Both models share the chromoly steel perimeter frame with WP USD front forks and WP PDS rear shock with no-linkage progressive system, delivering world-class handling on professional motocross tracks. The wet-sump lubrication system with oil jets cooling the piston undersides ensures reliability under sustained high-RPM racing conditions. Electric start standard on both models eliminates kickstarter hassle while keeping the overall weight minimal.
