KTM MOTORCYCLE EXC 450


Once a champion, always a champion. If one bike in the hard-fought E2 class has until now had what it takes to be the series winner, then that bike is the 450 EXC. And so it should stay! Ultra-modern technology is used both in the chassis and also in the ultra-powerful SOHC engine, which further perfects one of the most successful of off-road bikes.

The result is an extremely light, agile and immensely powerful high-tech race bike which once again raises the bar a whole step higher for the opposition.

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.
