The smallest KTM four-stroke mercilessly shows what it's made of. The latest four-valve technology gives the 250 EXC-F massive thrust from the bottom of the range up into the highest speed ranges. An extremely agile, light-weight muscleman that is a great success in the small class - not only in the world championships.
