The KTM 500 EXC is a series of 4-stroke enduro off-road motorcycle made by KTM. They are essentially the 400/450 EXCs with changes to the bore or stroke to achieve larger displacements. The 520, 525, 530 and 500 are all in fact 510.4 cc motors given different model numbers to distinguish them. Like the other KTM enduro offerings they vary in the set-up and components. The international EXC versions have a small headlight, speedometer, tail-light and somewhat softer linkless (PDS) rear suspension. As of 2008 the US version of the EXC continued to be sold in street legal trim but was replaced by the off-road only 500 XC-W for the US market. In 2012 the US 50-states street legal 530 EXC-R was rebadged the 500 EXC.
