2023 KTM 450 SMR Supermoto Review Specs

When milliseconds and centimeters matter more than lap times and overtakes, the 2023 KTM 450 SMR Supermoto is the perfect machine for every Supermoto enthusiast or competitor.

The first improvement is a better hydro-formed, laser-cut, and robot-welded frame. The focus and sensitivity of the front end and the solidity of the rear end characterize all that is strong and swift on the Supermoto circuit.

For input that each rider needs, from novice to world champion, KTM adjusted the torsional and longitudinal flex and increased the frame wall thickness. A revamped shock mount for 2023 enhances energy absorption and straight-line stability.

Thanks to the redesigned shock and the changed placements of the spinning masses, the “anti-squat” concept also allows for better acceleration and corner departure. With its “inward” positioned footrests, the 2023 KTM 450 SMR gives the rider the sensation that they may grasp, carry, and push the bike to their heart’s content.

The 2-piece aluminum subframe reinforced with polyamide is another part that improves handling and has excellent strength. The newly fitted, high-quality aluminum triple clamps have an extended grip surface to limit the handlebar “twist” and release the flow of contact with the track surface. The clamps were CNC-machined.

2023 KTM 450 SMR Supermoto – Features and Specs


The 2023 KTM 450 SMR Supermoto’s SOHC engine is among the most potent 4-stroke engines. It perfects every aspect of contemporary engineering.

Aside from the benefits of mass centralization and reduced engine weight, the chassis displays exceptional anti-squat characteristics for 2023, with the engine tilted 2° rearward and the front sprocket positioned lower.

You will leave the competition in your dust with an engine that weighs in at just 26.8 kg overall and produces over 63 HP at its peak.

Crankcases and engine covers

The 2023 KTM 450 SMR Supermoto engine’s principal design objectives were to reduce weight and centralize bulk. It is why crankcases are designed to secure the engine’s internal components in the most advantageous position for a center of gravity while minimizing their weight like in 2022 KTM 450 SMR.

High-pressure die-casting allows for more uniformly thickened walls while making the casings thinner. Finally, the KTM logo makes the black powder-coated engine cover seem VERY RACE-READY.


The 2023 KTM 450 SMR Supermoto has a SUTER slipper clutch that prevents the rear wheel from becoming unstable or hopping while braking hard at a curve’s apex, allowing for perfect Supermoto-style drifting and maximum control. Brake hydraulics provide flawless clutch modulation.

The updated lightweight 5-speed gearbox is made by Pankl Racing Systems, who promise the highest reliability and longevity. There was a noticeable decrease in operating effort during gear changes thanks to the weight-optimized shift shaft and the revised transmission ratio of 29:72.

Even under the worst conditions, the gear shift lever’s anti-dirt buildup mechanism will keep the lever tip where it is.

Engine Management System

Lightweight, small, and very fast in processing data were the primary goals when Keihin designed the EMS. You may choose the engine map with the handlebar map change button, use the Quickshifter function, and launch control to ensure perfect beginnings. It also includes traction control.

Additionally, it coordinates with the gear position sensor to optimize power delivery to each gear and the roll-over sensor (ROS) to further safeguard the 2023 KTM 450 SMR Supermoto by shutting off the engine in the case of a severe crash.

The hour meter now has an integrated fuel level indicator and an LED for the EFI status, which may assist you in deciding whether to stop into the pits for a refill.

Stop/Start Switch

Although you won’t need to, the 2023 KTM 450 SMR Supermoto’s integrated start/stop switch on the right side of the handlebar simplifies and rationalizes the operation.


The expert design of the 2023 KTM 450 SMR Supermoto exhaust system allows for class-leading performance with the minimum amount of weight. The two-piece header has a flow-designed resonance chamber, allowing for its removal without removing the shock absorber.

This will enable it to remain as compact as feasible. Thanks to technological advancements, a sleek, lightweight aluminum silencer can be manufactured without increasing noise levels.


The 2023 KTM 450 SMR Supermoto radiators are built with high-strength aluminum and use computational fluid dynamics (CFD) to improve airflow velocities. More uniform coolant flow is made possible by reducing system pressure via a big central tube that passes through the frame.

The cooling system is incorporated into the frame by eliminating the need for extra external pipes and channeling coolant through the frame, resulting in superior cooling. An integrated thermostat is standard equipment, which increases reliability.


Whatever the track conditions, you’ll maintain complete control thanks to the brand-new frame’s design, which is engineered for longitudinal rigidity and moves the center of gravity closer to the rotating mass. Frame walls with precisely measured thicknesses provide unrivaled riding comfort and superior flex characteristics.

A new shock mounting provides superior anti-squat behavior for better traction out of corners, and the footpeg mounting point has been moved inwards to lessen the danger of hooking up.


The two-piece subframe, constructed from 60% polyamide and 40% reinforced aluminum, offers exceptional handling and rider input.

The subframe is built with precise degrees of rigidity using finite element analysis, which allows for optimum flex dynamics, durability, and reliability lap after lap.


The hollow die-cast aluminum swingarm is designed to be lightweight while providing optimal stiffness and durability.

The rider may shorten the wheelbase for tighter courses or lengthen it for extra stability while going fast, thanks to the wide range of changes made possible by the rear wheel.

Maintenance is also a breeze thanks to the chain adjustment markers visible from above for easier access and measurement. A new 22mm rear axle is installed further to enhance the flex characteristics of the new chassis.


The 2023 KTM 450 SMR Supermoto has sturdy but featherweight black ALPINA spoked wheels, with front and rear measurements of 16.5 and 17 inches, respectively.

They are complemented by the Metzeler Racetec SM K1 Supermoto tyres, which are standard on the KTM 450 SMR. The front tires have a size of 125/75 R 16.5, while the back tires have a size of 165/630 R 17.

Fuel Tank

The 2023 KTM 450 SMR Supermoto’s 7.2-liter polythene fuel tank has a built-in gasoline pump and a cap that screws onto the tank. The fuel pump’s outside fuel line is carefully positioned to prevent damage and exposure while ensuring a continuous flow of gasoline.


The 2023 KTM 450 SMR Supermoto comes with NEKEN’s high-strength aluminium tapered handlebar. Featuring the same patterns as the tank spoilers and frame protectors, the newly designed KTM branded handlebar pad cushions unintended knocks and offers superb handling with the characteristic KTM bend. That is an elegant touch.


With their more extensive contact area, the newly designed footpegs by FEA make it easier to maintain control of the bike when standing on it. Furthermore, they are less prone to hooking up—while gliding or slanting downhill; a new, thinner mounting design for the frame allowed for this to happen.


Improved knee contact results from the 2023 KTM 450 SMR Supermoto’s redesigned rider triangle and enhanced gripping surfaces, especially while standing on the pegs. With its bright orange graphics and subtle purple accents, the 2023 KTM 450 SMR looks like it came straight out of the ’90s.

Handlebar Map Select Switch

The 2023 KTM 450 SMR has a map selector, allowing the rider to choose between two engine maps. Map 1’s power production is linear and predictable, unlike Map 2’s sharp and explosive power output. Using the same set of controls, the rider may access the new Quickshifter functions and launch and traction control.

Launch Control

With launch control, getting into the holeshot and off the line quickly is considerably more manageable. Press the quick-shifter and traction control buttons simultaneously to engage the launch control when the engine is idling. This function limits the power given to the rear tire during takeoff, which increases grip and reduces the wheelspin during high acceleration.

A Li-Ion 2.0 Ah battery and an easy electric starting mechanism are standard on the 2023 KTM 450 SMR Supermoto. Electric starting is made possible using the Li-Ion battery’s minimal weight, around 1 kg less than a conventional lead battery.
