New 2027 KTM 250SX

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:

• 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.

• ELECTRIC START

Picture this; Youre 7 laps into an absolute ripper of a race. You miss your line and end up stalling in a deep rut. But dont 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 riders seat, a high-quality starter & pickup and super robust design, the only thing youll be kicking - is ass.

• 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.

• PERFORMANCE

The KTM SX-F engine is tilted 2 backward, this means greatly improved mass centralization and reduced overall weight, benefiting handling and anti-squat behavior. A silencer offers an improved response in combination with the mapping switch and provides a slightly quieter exhaust note.

• 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.

• 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!
