KTM incorporates the new ones into its 2025 range 125 SMC R and 390 SMC Rtwo small displacement models that offer the accessibility and ease of use of a compact single-cylinder motorcycle while providing dynamic riding experiences with real-world usability.
To achieve this, they have, among others, a long-travel suspension, 17” wheels shod with tires with good grip and a specific selection of driver aids and technology, which provide us with a truly satisfactory driving experience.
New KTM 125 SMC R and 390 SMC R in detail
For this new year KTM renews its SMC R range with new elements in the different key points of both models. Starting with its 2-piece steel tubular chassis based on the Gen 3 platform used by the smaller displacement Duke models. For the occasion it presents a different steering angle, triple clamps, subframe supports and rigidity profile, designed specifically for Offroad use, with better handling, control and stability.
The new frame is also designed for greater clearance for the radiator package, with footpeg placement optimized to better suit riding style and the requirements of aggressive supermoto-style riding. They also debut a new subframe specifically designed to offer a one-piece seat. The new gravity die-cast swingarm is derived from the new generation Adventure range of lower capacity.
At the suspension level, the SMC R range has a 43 mm WP APEX inverted fork at the front, while at the rear we find a displaced monoshock. In both cases we have up to 230 mm of travel on both axles, and different settings if we talk about the 390 SMC R.
Braking on the KTM 125 SMC R and KTM 390 SMC R uses 320 mm radial discs at the front and 240 mm at the rear. The assembly is anchored to 17” wheels at each end, shod with 110/70 R17 and 150/60 R17 tires, front and rear respectively. While the KTM 390 SMC R has radial type wheels, the 125 SMC R is equipped with alloy wheels.
Mechanically, both SMC R models are powered by a new generation of single-cylinder engines that debuted in the recent KTM Duke range. These engines are completely redesigned, with newly optimized cylinder heads and gearboxes ready to comply with EURO 5+ regulations.
This new LC4c engine features a larger valve cover with a smaller cylinder head, reducing weight at the top end of the engine. A new thermostat position, mounted directly on the cylinder head, improves thermal control and provides more stable operating temperatures in different driving conditions.
The new injectors are now angled directly into the intake valves to reduce buildup in the intake runner. These new injectors also provide finer fuel spray, resulting in more efficient combustion and fewer emissions. A new airbox has also been optimized to fit the SMC R package.
This has been done to allow the engine to sit higher, increasing ground clearance and allowing for a more centered driver’s triangle. A unique stainless steel exhaust design means the system fitted to the KTM 125 SMC R and KTM 390 SMC R does not require a silencer.
This has meant a total weight saving of 2 kg. The new exhaust is equipped with a double catalyst to comply with Euro 5+ regulations and features active control whereby the ECU not only adjusts the fuel mixture for optimal detonation, but also adjusts the mixture to ensure a correct temperature. optimal for reducing emissions.
The active combustion system also works to detect any misfires, which helps diagnose the condition of the catalytic converter and store information for OBDII diagnostics. All this combined with a revision of the gearbox in which the movements of the gears along the axles are now smoother.
The shifter travel has also been reduced, resulting in quicker, more responsive action. The power-assisted slipper clutch is now fitted to all models, with optimized gearing in the clutch basket and flywheel that reduces weight and makes clutch control easier, along with an optional Quickshifter+ system.
In technological terms, the new KTM 125 SMC R and KTM 390 SMC R 2025 The KTM 390 SMC R 2025 have, among others, Full-LED lighting, as well as selectable driving modes. The default setting is STREET and for riders looking for more control, as well as SPORT mode where the Motorcycle Traction Control (MTC) can also be turned off completely.
All SMC R models are equipped with dual-channel ABS, this is thanks to the Bosch 10.3 MB modulator. If the rider selects SPORT mode, they can choose between Road, Supermoto or Supermoto+ABS. The KTM 125 SMC R does not have selectable riding modes.
The SMC R range comes with a new 4.2-inch TFT dashboard with connectivity features such as a music player via the KTM Connect app, the ability to answer incoming calls and turn-by-turn navigation. The new instrument panels are operated from a 4-way joystick with optimized ergonomics and illuminated switches.
Aesthetically, the 2025 KTM 125 SMC R and KTM 390 SMC R models feature all-new, Offroad-inspired styling, with a clear, definitive KTM CTG design in rugged in-mold graphics. The Austrian brand announces that the new KTM 125 SMC R and KTM 390 SMC R They will reach dealerships in early 2025, with an official price of 5,599 and 6,399 euros respectively..
