The 2003 to 2004 KTM 250 EXC is a two-stroke enduro that the listing describes as well built, with strong top-end power and better suited to off-road use than to public roads. Compared with the 2001 to 2002 bike, it has a 66.4 x 72.0 mm bore and stroke (the earlier bike is 67.5 x 69.5 mm), an 11.0:1 compression ratio, and a lighter 102.5 kg dry weight. It keeps the kick start and a 5-speed gearbox.
