Motorcycle specifications KTM450 SMR 2026 Tearing up the soil

For most motorcycles, one of the constraints is compliance with Euro-machine standards. For the 450 SMR, it's the FIM that she's looking to. As the FIM has set a noise limit of 109 dB, the Katoche adapts to meet this ceiling (EFI modification, injection, airbox, silencer). Fortunately, it loses nothing in the way of power.

Other improvements include

• Simpler, faster maintenance, thanks to a new radiator closure system
• New protective cap on fuel connector
• New optional Connectivity Unit Offroad (CUO) module. Via the KTMConnect application, it can be used to modify engine parameters, aid suspension adjustment and track mileage. Thanks to the integrated GPS, drivers can also analyze their riding style and performance.

An established benchmark

With its 450 SMR, KTM has a real Supermot' nugget, full of energy and ready to unleash continuous jets of adrenalin. The SMR is a benchmark in the supermotard world. Combining cutting-edge technology with KTM's race-proven engineering, the upgraded 2025 version offers formidable performance, agility and power.

Using the recently updated KTM 450 SX-F 2025 as a base, the KTM 450 SMR raises the bar even higher, with key improvements to the frame, fork and ergonomics.

With its 63 hp, 450 cm3 SOHC engine, the 450 SMR has benefited from a series of upgrades like those found on the recently updated KTM SX-F 2025 range. The biggest and most significant of these are to be found on the frame, with visible cut-outs and changes in tube wall thickness around the front end, engine and rear shock mounts.

In addition to a 300g weight saving, these structural modifications have been designed to improve chassis flex characteristics and cornering behavior, while maintaining overall stability. On the latter point, smaller footpegs since 2025 maximize lean angles and reduce the risk of snagging on track edges.

The 450 SMR comes standard with launch control and Quickshifter. Launch Control limits power to the rear wheel, improving traction and preventing loss of control during hard acceleration. To activate, simply press the launch control and quickshifter buttons simultaneously.

The 450 SMR's map selector has been simplified, making it easy to choose between the 2 engine maps. Mode 1 offers a more linear power curve. Mode 2 is more responsive, with more aggressive throttle response and explosive power. Traction control is easily activated and deactivated from the same switch. It guarantees maximum traction and offers an undeniable advantage on slippery terrain.

The 4? SMR also features a 48 mm WP XACT adjustable closed-cartridge fork. This features a centrally-valved piston design that optimizes oil flow in the cartridge and prevents the formation of unwanted oil foam, thus preserving damping characteristics. A hydraulic stop in the last part of the stroke preserves maximum reserves in extreme scenarios, such as bigger jumps or hard landings.

At the rear, a WP XACT rear shock absorber benefits from an updated linkage with renewed seals and smaller-diameter linkage bolts. The configuration comes directly from the KTM Factory Racing team and has been thoroughly tested on both gravel and asphalt.

Ergonomically, the KTM 450 SMR benefits from tank fairings with bi-composite plastics on the upper and lower sides. This not only gives it a distinctive look, but also contributes to cooling by channelling air more effectively.

As for the air intake, an updated one-piece intake sleeve and snorkel design prevent distortion, thanks to a stronger, stiffer construction, while an updated fuel tank roller protects the frame from wear and improves tank fit.

Above the surface, an all-orange body, with red and black molded graphics, and a stronger black saddle bring a sleeker look while communicating the SMR's pure READY TO RACE intentions.

Like previous generations, the 450 SMR is equipped with race-ready Metzeler Racetec SM K1 Supermoto tires, wrapped around lightweight ALPINA rims measuring 16.5" at the front and 17" at the rear.

The brakes are worthy of a half-superbike. High-performance Brembo components deliver incredible stopping power, with a radial-mount 4-piston M50 caliper and radial master cylinder holding an imposing 310 mm disc at the front. A single-piston caliper and 220 mm disc provide braking power at the rear.
