2025 KTM 450 SMR

The 2025 KTM 450 SMR represents the only real all-aspect form of motorcycle sport. Taking all the best bits from the championship-winning KTM 450 SX-F and adding more asphalt bias like racing slicks, big brakes, and top-notch suspension. Simply put, it's READY TO RACE in the very purest form.

Features may include:

At the startline
  • 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

The 2025 KTM 450 SMR features one of the most exhilarating 4-stroke engines in the paddock, with its SOHC powerplant exemplifying cutting-edge engineering. With a peak power output of over 63 HP and an overall engine weight of only 26.8 kg, you'll leave the competition eating your dust. The silencer offers exceptional response in combination with the mapping switch and provides a slightly quieter exhaust note. For those looking for more, a quick visit to the KTM PowerParts catalog with give you a proper A-SMR experience.

Compossed under pressure
  • Absolute Control

Get ready for an all-out apex assault. The 2025 KTM 450 SMR has 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 years, with renewed engine mounts. This adds up to a 300g weight saving and improved flex for better cornering.

Hit The Big Stuff
  • Updated Suspension Settings

For 2025, the KTM 450 SMR has given the WP XACT Closed Cartridge forks and WP XACT rear shock an update. Lining up at the starting grid with reworked settings and reduced weight, with improved weight distribution and increased overall response.

Maintaining Momentum
  • Footpegs

Newly designed footpegs have been added to the 2025 KTM 450 SMR's arsenal. These feature a slightly smaller surface area, making them less susceptible to hooking up on track curbs, and make better control when cranked right over.
