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.


EXC SIXDAYS

Engine
The SIX-DAYS models draw their power from two-stroke and four-stroke racing engines which have been optimised down to the finest detail for Enduro racing. Powerful, with perfect power delivery and excellent durability. Pure energy!

Tank
Ergonomic tank for ideal contact with the bike. Special KTM airflow system with ducts beneath the spoilers for an optimum fresh air supply to the airbox. Another advantage for racing: transparent polyethylene lets you see the fuel level from the outside.

Seat
The seat of the Six-Days bike is supplied with additional pockets and logos. It also has a reduced-weight, optimised foam core for improved comfort and longer service life.
