Two years of hard-charging R&D have gone into the making of the 2025 KTM 125 XC. That’s right, we meant Racing and Development. A reworked, lighter frame, updated engine mounts, and a new durable chain glide – to name a few – make the 2025 KTM 125 XC the leader in the 2-Stroke GNCC screamer class.

Engine

Designed to churn out more torque than any 125 cc 2-Stroke on the market, the 2025 KTM 125 XC is set to continue its dominance in its class with unrelenting forward momentum. With an overall engine weight of only 39.37 lb and impressive horsepower figures, this lightweight powerplant retains its typical high-revving character, while laying down the grunt where it matters most.

Chassis and Suspension

The 2025 KTM XC and XC-F range receive some major frame updates directly from Factory Racing efforts. For starters, the frame area around the rear shock mount has been updated, and more streamlined. The front area of the frame is also updated. with a different wall thickness compared to the previous model year, with renewed engine mounts. This adds up to a 300g weight saving, and improved flex for better cornering behavior.

Styling

The 2025 KTM XC and XC-F range feature upgraded tank shrouds with bi-compound plastics, which work alongside the specially-developed rider triangle, to provide unmatched knee contact and gripping surfaces – especially when standing on the pegs. While the plastics work to expel mud buildup in wet, muddy conditions, the flat seat profile and high-grip orange seat cover give exceptional rider movement and control. A handy grip pocket under the seat, just above the airbox, makes gripping the bike and lifting it much easier.
