The track-only KTM 450 SMR, built on the platform of the KTM 450 SX-F, has been updated for 2025, with improvements to the frame, fork, and styling.

The most significant update to the KTM 450 SMR is the frame, which now has visible cutouts and tube-wall-thickness changes around the front. The engine and rear shock mounts have also undergone some changes. These upgrades shave a bit of weight off the bike, which weighs 240 lb without fuel, while also improving chassis flex characteristics and cornering behavior, according to KTM. Also new are smaller footpegs to maximize lean angles.

The SMR’s suspension has also been updated for 2025. The previous AER 48mm fork has been replaced with a fully adjustable 48mm WP XACT closed-cartridge spring fork with a new mid-valve piston concept for optimized oil flow. The new hydro stop in the last part of the stroke is said to help keep a maximum of reserve for scenarios like big jumps and hard landings. The WP XACT shock returns with an updated linkage featuring new seals and smaller-diameter linkage bolts. Suspension travel is 11.1 inches in the front and 10.4 inches out back.

Air intake has improved with a one-piece inlet sleeve and snorkel design to prevent deformation thanks to a more robust and stiffer construction. The updated fuel tank mount is said to help protect the frame. Fuel capacity is 1.9 gallons.

The bike also receives new tank shrouds with bi-composite plastics on the upper and lower flanks, which contribute to the SMR’s new look. The full-orange bodywork with red and black graphics and a black seat, which KTM says is more durable than the previous seat, also contribute to the bike’s updated look.

Returning to the SMR are the Metzeler Racetec SM K1 Supermoto tires, which replaced the Bridgestone tires used since the 2023 update. The Metzelers are wrapped around 16.5-inch front and 17-inch rear wheels.

The KTM 450 SMR remains powered by a liquid-cooled 449.9cc Single with SOHC that makes a claimed 63 hp. Braking is provided by Brembo, with a 310mm front disc paired with a 4-piston radially mounted caliper. The bike also features a quickshifter that allows clutchless upshifts from 2nd to 5th gears, two ride modes, traction control, and launch control.

What’s new on the 2023 KTM 450 SMR?

The 450 SMR’s revised shock mount is said to enhance energy absorption and straight-line stability, and its “anti squat” design should translate to better acceleration and stronger corner exits. Redesigned high-grade aluminum CNC-machined triple clamps have increased grip surface for less handlebar “twist,” which should contribute to better control and feedback.

The SMR’s central double-cradle-type chromoly steel frame is still hydro-formed, laser-cut, and robot-welded, but KTM has altered longitudinal and torsional flex as well as frame-wall thickness to improve feedback. The new 22mm rear axle and latest generation of WP XACT suspension are said to improve traction and energy absorption for sliding into turns.

The fully adjustable AER 48mm front fork with 11.2 inches of travel still has a split-damping function and simple toolless adjusters, among other advantages. Out back, the 2023 model features a shorter, lighter (but still with the same 10.5 inches of travel) WP XACT shock, which has revised internals to improve damping behavior.

Replacing the Bridgestone slicks are Metzeler Racetec SM K1s, which promise rapid warm-up times and consistency in grip lap after lap. The 450 SMR rolls on Alpina tubeless spoked wheels, with a 16-inch front and a 17-inch rear.

The 499.9cc liquid-cooled, SOHC Single, which still blasts out a claimed 63 hp, has been revised to improve mass centralization and reduce weight – at 59.5 lbs, it’s nearly a pound lighter than the previous version. The engine has been tilted back, the cylinders have new internals, the crankshaft has been optimized, and the countershaft sprocket has been lowered by 3mm. Pankl Racing Systems has supplied a redesigned 5-speed gearbox with new ratios.

Another feature is the new Quickshift sensor on the shift drum for clutchless upshifts, which can be disabled through the handlebar switch. The Keihin Engine Management System still administers the traction control, launch control, and quickshifter functions, and there are two customizable engine maps.

Throwing the whole package into place on-track is easier thanks to revised ergonomics and a sculpted rider triangle that permits an even better contact points between motorcycle and user. There’s also a new recessed grip pocket under the seat, and visually, the 1990s-derived splash of purple adds to the “Ready to Race” graphic vibe, along with the flat orange seat and white tailsection.

Where does the song remain the same?

KTM follows the old adage “If it ain’t broke, don’t fix it” with several aspects of the new 450 SMR. The polyamide-reinforced aluminum two-piece subframe is strong, light, and contributes to a sense of control from the saddle, as do the inward-located footpegs that are cleated to ensure reassuring grip under extreme riding conditions.

Premium components such as the Brembo M50 monoblock 4-piston front caliper with a 310mm rotor, a 220mm rear disc with a 1-piston caliper, a Suter slipper clutch with Brembo hydraulics, and a compact exhaust system ensure that the 450 SMR is ready to compete right out of the gate.

Full specs have not yet been released, but expect a slight reduction in weight from its predecessor (232 lbs) with the same 35-inch seat height and 1.85-gallon fuel capacity.

The 2023 KTM 450 SMR will be available starting in June 2022. Visit ktm.com for more details and to find a dealer near you.
