...for born champions.
As one of the most successful Enduro bikes of recent years, the 450 EXC still has but one aim in the E2 class: the world championship title. A new frame design, the perfected settings and an ultra-powerful SOHC engine with the latest technology once again raise the bar for the competition.

Extremely light, ultra-agile and with endless power – the signs of a champion in 2010!

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.
