2027 KTM 300 SX Features & Technology

Electronics that simplify race-day setup

The 2027 KTM 300 SX uses an Electronic Fuel Injection system with Keihin EFI and a Vitesco Technologies engine management system (EMS). For riders, the big benefit is consistency: the bike is designed to deliver reliable fueling without the constant jetting changes that used to be part of living with a high-performance 2-stroke.

KTM also pairs EFI with a power valve to broaden usable power and improve rideability. That smoother, more controllable delivery can help the rear tire find traction when the track gets slick or choppy—especially when you’re trying to keep the bike driving forward instead of lighting up the tire.

If you want the full story on how the engine feels on track and how the gearing plays into it, see the Performance Guide.

Map select: two personalities at your thumb

The KTM SX models feature a map select switch that lets you choose between two engine maps. In practical terms, it’s a quick way to tailor response to conditions—think a more predictable feel when the track is hard-packed and slippery, or a sharper hit when you want maximum urgency out of corners.

Because it’s a switchable setting, you can adapt between motos or even during a ride day without turning the bike into a “project.” It’s a simple feature, but it’s one that riders notice when the track changes through the day.

Electric start and race-ready controls

Electric start is standard on the KTM SX models, giving you a fast restart after a stall without burning energy on the line or in a rut. It’s the kind of feature that matters most when you need it immediately—mid-moto, in traffic, or after a mistake—so you can get rolling again with minimal delay.

Clutch feel and modulation are handled by a DDS multi-disc wet clutch with Brembo hydraulics. Hydraulic actuation is valued for consistent lever feel as conditions heat up, and it helps riders keep engagement predictable when they’re finessing traction out of corners or managing fatigue late in a moto.

Ergonomics and bodywork designed for grip and movement

KTM’s SX bodywork is shaped around a purposeful rider triangle and designed to support strong knee contact when you’re standing and weighting the bike. The goal is a secure, repeatable interface—so you can move forward for corner entry, get centered for braking bumps, and shift back for drive without feeling like you’re fighting the plastics.

The tank shrouds use bi-compound plastics intended to channel air toward the radiators while also improving durability. KTM also calls out a tighter fuel tank “roll,” aimed at giving a more secure fit and reducing the chance of frame scrubbing during aggressive movement.

Chassis layout and frame design details are covered separately on the Suspension & Chassis Breakdown.

Ownership-friendly service access and durability details

KTM highlights serviceability across the SX range, focusing on easy-to-access service parts and trackside-friendly adjustability. The idea is straightforward: less time wrestling with maintenance tasks and more time riding—whether you’re a racer doing quick checks between motos or a newer rider learning to handle your own upkeep.

On the EFI side, KTM notes a fuel protector cap designed to keep maintenance access quick while adding protection against impact, accidental opening, and dirt ingress around the connector area. KTM also calls out a threaded radiator cap intended to make opening easier and faster with reduced force.

For 2027, KTM mentions modified wiring harness fixing points and routing to make the harness less prone to wear and damage. It’s a small, practical detail that matters over a season of washing, transport, and repeated vibration.
