High-performance enduro bikes are always in great demand, especially if it’s to be used in competitive races like the Extreme Enduro or the E2 World Championship. When that’s the case, KTM has a solution for one of the best enduro bikes on the market today: the 250 EXC.
Built with the ideal combination of performance and weight, the serial Erzberg winner is the enduro to beat when you’re in need of a highly competitive bike. For 2012, the bike comes with improved performance courtesy of a redesigned airbox and the flow-optimized intake flange between the airbox and the carburetor that ensures improved charging with fresh gas. Together, these features result in even freer revving and even more power in all rev ranges, making for one of the most powerful two-stroke machine in its class.
In addition to the improved performance, the 250 EXC also comes with a completely revamped chassis with a new frame and the latest WP upside-down fork with wider adjustment ranges and a new setting. All the performance and suspension improvements make the 250 EXC a bike that’s practically unbeatable in terms of weight, mechanisms, and overall stability.
There’s not a lot of things about the KTM 250 EXC that speaks of mediocrity. Certainly, anybody that rides this bike will attest that it’s one of the most rounded and versatile in its class.

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 an optional switch.
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.
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.
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.
New Swingarm, New PDS and New Setting
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.
