The two-stroke bike maven is a real torque-wonder, possessing unbelievable power stemming from its 300cc 1-cylinder 2-stroke engine. Combine this scintillating piece of engine performance with a revamped chassis and you have an endure bike that’s been prepped to get down and dirty with the best of its class in the market.

Engine

KTM 300 EXC
  • 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. Unrivaled performance and playful handling are the results.
  • Together with the redesigned airbox and flow-optimized intake flange between airbox and carburetor, 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.
  • 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 an optional switch.

Bodywork

KTM 300 EXC

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.

New Frame

KTM 300 EXC

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 300 EXC have been further optimized.

New Swingarm, New PDS and New Setting

KTM 300 EXC

The 300 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.

Quotes

KTM PartsOnline----"Whether in the Extreme Enduro or the E2 World Championship, the 300 EXC is the ultimate victory machine. Built with the ideal combination of performance and weight, the serial Erzberg winner is the enduro to beat when the going gets really tough. Improved performance mounted in a completely revamped chassis, with a new frame, upgrades the lightest enduro in the E2 class even further. Proof on two wheels that the two-stroke machines from KTM are also to be reckoned with in future."
