The supermoto scene gets an electrifying upgrade for 2025 with the introduction of the KTM 125 SMC R and KTM 390 SMC R. These compact single-cylinder bikes promise accessibility and ease of use while delivering dynamic, adrenaline-packed riding experiences. True to KTM’s READY TO RACE ethos, these models offer real-world usability without compromising on the thrills. With 17” wheels and a meticulously selected suite of rider aids and tech, they deliver sporty, rider-friendly performance that’s just as fun on the streets as it is on the track.
Design and Bodywork
Sleek, compact, and purpose-built, both models feature slimline fairings and a 9L metal fuel tank designed for optimized rider ergonomics and durability. Whether you’re leaning into corners or riding on the pegs, the minimalist design ensures you’re in complete control. The new off-road-inspired styling is further enhanced with durable in-mold graphics that underline KTM’s distinctive aesthetic.
Chassis and Suspension for Superior Control
Built on a re-engineered Gen 3 steel trellis frame, the SMC R models offer exceptional handling, stability, and control. Designed with a sharper steering head angle and improved rigidity, the frame is tailor-made for aggressive supermoto-style riding. A bolt-on steel trellis subframe complements the setup, ensuring durability and practicality with a sleek design.

The KTM 390 SMC R provides effortless compression and rebound adjustability in 30-click increments, while the 125 SMC R features a fixed setup for simplicity. At the rear, both bikes use an offset WP APEX shock absorber, with rebound and preload adjustability on the 390 SMC R.
