IT'S HUNTING SEASON

When it comes to power-to-weight ratios, the KTM 300 SX writes the rule book. Now with learnings taken directly from the KTM Factory Racing teams, and a care package labeled ""Go get 'em!"", the KTM 300 SX is engineered for one task alone - to lead from the front.

Features may include:

CLICK INTO ACTION
  • EASY SUSPENSION ADJUSTMENT

As always, the suspension boasts an easy tool-free setup at both ends, ensuring you chase down the podium in total control. On the rear, a hand-adjustable dual compression option allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily modified thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.

CHUGGA CHUGGA, RING DING DING!
  • ELECTRIC START

Picture this; You're 7 laps into an absolute ripper of a race. You miss your line and end up stalling in a deep rut. But don't sweat it. All you do is press the starter button and you blast off again to take the flag. This is the reality on the KTM SX models. Thanks to a 12,8V 2 Ah lithium ion battery is placed under the rider's seat, a high-quality starter & pickup and super robust design, the only thing you'll be kicking - is ass.

LESS FOCUS ON THE TOOL, MORE FOCUS ON THE TRACK
  • SERVICEABILITY

The KTM SX and SX-F range is engineered and designed to provide riders with easy-to-access service parts, as well as suspension adjustability. This permits faster trackside and off-season maintenance, as well as simplifying motocross for novice riders without pit crews. For 2026, a new threaded radiator cap allows easier and faster opening with reduced force.

UNMATCHED PERFORMANCE
  • PERFORMANCE

The 300 cc 2-stroke powerhouse brings a only choice of weapon into the MX Open category and provides more choice for racers looking for maximum power at the least possible weight. Along with low maintenance costs, an overall engine mass of just 23,9 kg the KTM 300 SX provides pure performance. And then some.

PICK YOUR POWER
  • SELECTABLE MAPS

The KTM SX models features a map select switch allowing the racer to switch between 2 engine maps. Map 1 provides a linear, predictable power delivery, while Map 2 gives it the full beans with crisp, explosive power output.

SMOOTHER POWER DELIVERY
  • EFI + POWER VALVE

With EFI comes great rideability. Along with the electronic fuel injection and a power valve on the KTM SX models, allowing for more usable power throughout the rev range. Smoother power means better traction. Better traction means holeshot heaven!
