2010 KTM 450SX-F

This isn’t just a bike, it’s a racing machine that is instantly the main contender on all tracks. With an ultra-light electric starter, a brand new 5-speed gearbox, new CNC-machined triple clamps and a new high-level chassis, the 450 SX-F makes the other bikes on the track look outdated, before and after the race.
