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.

Airbox

Designed to provide maximum airflow, the new air filter box is designed with precisely positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. The Twin Air filter and air filter support design feature a simple fail-proof mounting system for safe and accurate filter installation, ensuring the air filter is easily accessed, without tools, by removing the left side panel, for easy track-side maintenance.

Serviceability

The KTM 450 SMR is engineered and designed to provide riders with easy-to-access service parts, as well as suspension adjustability. This allows for faster track-side and off-season maintenance, as well as making supermoto more accessible for novice riders without pit crews. For 2026, a new threaded radiator closure allows for easier and faster opening with reduced force.

More Usable Power

The KTM 450 SMR features one of the most exhilarating 4-stroke engines in the paddock, with its SOHC powerplant exemplifying cutting-edge engineering. 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 will take things to the next level.

Launch Control & Quickshifter

Launch control, ENGAGED! Designed for total domination, the KTM 450 SMR comes fitted standard with launch control and Quickshifter functionality. Launch control is easily engaged by pressing the traction control and Quickshifter buttons simultaneously and works by limiting the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration. Meanwhile, the Quickshifter function means you can bang through from 2nd to 5th gear with your focus solely on getting to the corner first.

Selectable Maps + TC

The map select switch on the KTM 450 SMR features a simpler design, allowing for easier functionality in switching between 2 engine maps. Map 1 provides a more linear power curve, while Map 2 punches all-out with aggressive throttle and explosive power. Luckily, Traction Control is easily toggled to an on or off position from the same switch, ensuring maximum traction and a distinct advantage in slippery conditions.

Absolute Control

The KTM 450 SMR frame is built for riders who demand sharp handling and full control. Its refined flex characteristics let you carve berms, launch jumps, and tackle technical terrain with confidence. A streamlined rear shock mount boosts stability and traction, while optimized engine mounts and wall thickness ensure a balanced, responsive feel from front to back.

Ergonomics

Tank shrouds using bi-compound plastics channel air towards the radiators more efficiently, while a concise fuel tank roll, makes for a tighter, more secure fitment, reducing the chance of frame scrubbing and dramatically improving durability. All this works alongside the specially-developed rider triangle, to provide unmatched knee contact and gripping surfaces - especially when standing on the pegs.

Performance

The KTM 450 SMR engine is tilted 2° backward, resulting in a 3mm lower front sprocket position. All of this means greatly improved mass centralization and reduced overall weight, benefiting handling and anti-squat behavior.

Slipper Clutch

The KTM 450 SMR features a SUTER slipper clutch which prevents rear wheel instability and hopping when aggressively down gearing for the apex. The result is maximum control, and the ability to perform the perfect Supermoto-style drifts into corners. What's more, a Brembo hydraulic system guarantees perfect clutch modulation - when you're not using the Quickshifter, that is.

WP XACT Fork

For the first time, a WP XACT Closed Cartridge fork finds its way into the KTM 450 SMR. Fast and consistent damping characteristics are guaranteed thanks to a new mid-valve piston concept which optimizes the oil flow within the cartridge. The WP XACT Close Cartridge fork comes with 48mm of diameter while the total length is now 925mm. As always, the fork is fully adjustable in rebound and compression. Hand adjustable clickers on the bottom of the fork shoe and fork top cap allow riders to change settings on the fly without the need of tools.

WP XACT SHOCK

Keeping things in check at the rear is the job of the WP XACT rear shock. Frame and shock geometry are optimized ground clearance at the linkage, making it less susceptible to bottoming out. Small diameter linkage bolts save weight, while new linkage seals refine rear shock response and advanced damping characteristics.

Wheels and Tires

Here's looking at you, slick. Black, high-strength ALPINA rims with CNC machined hubs, and lightweight spokes, are wrapped in Metzeler Racetec SM K1 Supermoto tires as standard. Thanks to the tire's ultra-fine silica compound, they warm-up fast and deliver exceptional grip on all surfaces.

Brakes

Think of it as half-superbike brakes. Exceptional stopping power is guaranteed by high-performance Brembo components, with a 4-piston radial mounted caliper and a radial master cylinder working together to grab a massive 310 mm disc at the front. A single-piston caliper and a 220mm disc provide the stopping power at the rear.

Connectivity Unit Offroad

Available as a PowerPart on the KTM 450 SMR, the Connectivity Unit Offroad - or CUO for short - offers a wide range of functionalities and adjustability options via the KTMconnect app. The CUO gives you a new insight into your riding, allows you to alter your engine behavior, and even provides you with optimized suspension settings based on individual preferences and riding conditions. Welcome to the next level moto.

Footpegs

The KTM 450 SMR features compact footpegs designed for precision and performance. Their reduced surface area minimizes the chance of hooking on track curbs, while enhancing control during deep lean angles, giving riders the confidence to push harder through every corner.

Consistency

The KTM 450 SMR is equipped with a robust chain guide and guard designed for maximum durability and consistent performance. Their streamlined design reduces the risk of hooking on external objects, ensuring smooth power delivery and reliability - lap after lap.

Energy absorption

Besides the expertly crafted, hydro-formed, laser-cut, and robot-welded frame being engineered to provide exceptional rider feedback and straight-line stability, it consists of specifically calculated parameters of longitudinal and torsional flex. This means the frame acts as a "shock absorber" of sorts, making for a less harsh ride, resulting in less rider fatigue over many hard laps.
