If at any point you begin to wonder how your enduro bikes are letting you down, maybe it’s time to find a suitable replacement for it. Maybe a replacement that not only is a significant upgrade, but is also considered one of the best in the market.

In the world of 250cc enduro bikes, the KTM EXC Six Days has the pedigree and wherewithal to be a talked-about bike many years from now. The name "Six Days" attached to it is an ode to the world’s largest enduro competition, the "International Six Days Enduro."

Six days in succession, over a thousand offroad kilometers, and 40 hours in the saddle is as grueling a test as there is, not only for the rider but for the bike as well. Fortunately, the 250 EXC Six Days offers a whole package of special high-quality options that makes it fit for the ruthless competition.

The 250 EXC is equipped with the latest WP upside-down fork with wider adjustment ranges and a new setting. The sensitive responsiveness and outstanding damping of the open-cartridge fork with 48 mm (1.89 in) outer tubes are a perfect complement for the 250 EXC’s playful handling and precision.

Practically unbeatable in terms of weight and stability, the 250 EXC also comes with new wheels that carry CNC-machined hubs, new black-anodized rims from Giant with black zinc/nickel-coated spokes. They have also reduced the unsprung and gyroscopic masses, hence bolstering the playful handling of the 250 EXC.

The responsiveness of the 250 EXC Six Days’ 250cc, high-torque two-stroke machine can be varied in three stages by replacing springs in the TVC exhaust controller, allowing the rider to choose between two different ignition curves by means of a plug or a handlebar switch fitted as standard.

The responsiveness of the high-torque two-stroke machine can be varied in three stages by replacing springs in the TVC exhaust controller. The rider of the 250 EXC can also choose between two different ignition curves by means of a plug or a handlebar switch fitted as standard.

The redesigned airbox on the 250 EXC and the flow-optimized intake flange between the airbox and the carburetor now ensure even better charging with fresh gas. This results in even freer revving and even more power in all rev ranges for the most powerful two-stroke machine in its class.

Chassis and Suspension

The completely revamped frame made from high-quality chrome-molybdenum steel is characterized by even greater lateral stiffness. It is also even better at absorbing jolts introduced by the suspension system, whereby the playful handling and comfort of the 250 EXC have been further optimized.

The 250 EXC’s new, lighter, cast aluminum swingarm accommodates the shock absorber more centrally, in order to load the swing arms more evenly. The new, 7 mm (0.28 in) longer PDS shock absorber with adjustable rebound and high/low-speed compression damping, and a new setting is installed more flatly, so providing even more progression.

The 250 EXC’s new bodywork with the very slim seat and spoiler lines, plus excellent contact points, perfects the bike’s ergonomics, making handling even simpler and more precise. The longer rear fender protects the rider even more effectively from swirled up stones.
