The KTM 300 EXC Six Days was especially designed to compete in the "International Six Days Enduro". This competition is a tough test as it means that the bike needs to withstand the punishment of off-road track for six days in a raw covering over a thousand kilometers. A whole package of high-quality special options makes the 300 EXC fit for this ruthless contest, in which more than half the starters bank on KTM every year.

One of the most important features of the 300 EXC is the latest WP upside-down fork which comes 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 300 EXC’s playful handling and precision.

Other modifications include the new wheels with CNC-machined hubs, new black-anodised rims from Giant, black zinc/nickel-coated spokes and ultra-light aluminum nipples.

  • The understandable technology of the two-stroke engine has indisputable advantages, including a high power/displacement ratio and low weight. In terms of power-to-weight ratio, the 300 EXC is practically unbeatable thanks to the latest facelift. Unrivalled performance and playful handling are the results.
  • 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 300 EXC can also choose between two different ignition curves by means of a plug or a handlebar switch fitted as standard.
  • Together with the redesigned airbox and flow-optimised intake flange between airbox and carburettor, the new cylinder with low valve timing ensures even better charging with fresh gas. This results in even freer revving and even more power in all rev ranges for the liquid-cooled, two-stroke machine.

New Frame and Suspension

  • The completely revamped frame made from high-quality chrome-molybdenum steel is characterised 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 300 EXC have been further optimised.
  • The 300 EXC’s new, lighter, cast aluminium 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 300 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.
