KTM 250 EXC 2017

KTM 250 EXC 2017

It wasn't just the looks of the KTM 250 EXC that convinced the 1000PS offroad faction. The 2-stroke single-cylinder was praised for its high torque, pleasant power and refined running. The behaviour of the chassis was also convincing, except for the excessive rebound of the fork. Thus, the KTM 250 EXC shines not only with a comfortable seating position but also with neutral and good-natured handling.
