2025 KTM 450 SX-F Base

2025 KTM 450 SX-F

When you see the 2025 KTM 450 SX-F roll off the trailer, you know it means business. With 5 AMA 450 Supercross titles in the last 7 seasons, the 2025 KTM 450 SX-F rolls up to the starting gate already armed with the learnings of past championships - only this time, it's freshly loaded with an all-new arsenal of weaponry.

Features may include:

BEFORE THE GATE
  • 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 control allows riders to adjust high- and low-speed settings in a matter of seconds. The forks on the front end are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and top cap.

START STRONG
  • More Usable Power

When the war drums sound and the gate drops, you need to be the first to off the line in a bid to rule the roost. The 2025 KTM 450 SX-F boasts one of the most manic 4-stroke powerplants in the paddock, with its SOHC engine proving to be the perfect example of advanced engineering. With a massive peak power output, and an overall engine weight of only 59 lb (26.8 kg), you'll leave the competition with more than a little mud on the face.

CALM UNDER FIRE
  • Absolute Control

Get ready for a full-on berm assault. The 2025 KTM SX and SX-F machines have received major frame updates directly from Factory Racing efforts. For starters, the frame area around the rear shock mount has been updated and made more streamlined, with new engine mounts and cut-outs for improved chassis flex. The front area of the frame is also updated. with a different wall thickness than the previous model year, with renewed engine mounts. This adds up to a 300g weight saving and improved flex for better cornering.

HIT THE BIG STUFF
  • WP XACT Fork

For 2025, the KTM SX and SX-F range has given the WP XACT AER fork and WP XACT rear shock an update. This means you'll be lining up at the setting gate with re-tuned settings, reduced weight, improved weight distribution, and an increase in overall response.

MAINTAINING MOMENTUM
  • Connectivity Unit Offroad

Available as a PowerPart on the KTM SX-F range, the Connectivity Unit Offroad - or CUO for short - offers a wide range of functionalities and adjustability options via the KTMconnect app. The CUO gives you a new insight into your riding, allows you to alter your engine behavior, and even provides you with optimized suspension settings based on individual preferences and riding conditions. Welcome to the next level moto.
