You'd be forgiven for thinking the KTM 450 SMR couldn't possibly get any better. But we'll let that slide - just as you would be doing when you throw a leg over the latest iteration of pure READY TO RACE perfection. With a frame that is specifically engineered for longitudinal rigidity, stability, and exceptional rider feedback and an engine that blows away the competition with unrelenting power delivery - not to mention the electronic wizardry to rival sports bikes - The KTM 450 SMR is a purpose-built racer with one simple goal - winning championships.

• Engine

The 2023 KTM 450 SMR boasts one of the most manic 4-stroke powerplants in the paddock, with its SOHC engine proving to be the perfect example of advanced engineering. For 2023, the engine is tilted 2° backward with a lower front sprocket position, which together with the benefits of mass centralization and reduced engine weight make the anti-squat behavior of the chassis second to none. With massive power output and an overall engine weight of only 59 lb, you'll dominate the competition apex after apex.

• Cylinder head

A completely redesigned SOHC cylinder head makes for a more compact and lightweight package, using a shorter profile with the camshaft located closer to the center of gravity. Lightweight valves are actuated via a DLC coated rocker arm with optimized timing, specifically designed to deliver precise levels of torque and throttle response. The diameter of the inlet valves is 40 mm, while on the exhaust it is 33 mm. Redesigned intake ports allow higher flow coefficients, resulting in a more efficient and powerful engine, with a new valve cover reducing the number of mounting screws, and a single oil spray jet guarantees efficient cooling while keeping the weight low.

• Exhaust

The KTM 450 SMR exhaust system is expertly designed to deliver class-leading performance at the lowest possible weight. Featuring a flow-designed resonance chamber integrated into the 2-piece header, the header remains as compact as possible with the joining position allowing it to be removed without having to take out the shock absorber. Further innovation allows for a short, lightweight aluminum silencer without increasing noise levels.

• Frame

No matter how twisty or technical the track is, you'll stay in complete control thanks to an all-new frame design that has not only been engineered for longitudinal rigidity but also repositions rotating mass closer to the center of gravity. Precise frame wall thicknesses deliver superior flex characteristics and offers an unmatched rider feel. A new shock mounting also provides improved anti-squat behavior to better traction out of corners, while the footpeg mounting position has moved inwards for less risk of hooking up.

• Subframe

The 2-piece polyamide (60%) reinforced aluminum (40%) subframe provides outstanding handling and rider feedback. Constructed with the aid of finite element analysis, precise levels of rigidity are engineered into the subframe, delivering optimal flex dynamics, while remaining robust and reliable lap after lap.

• Handlebar

The KTM 450 SMR is equipped with a tapered handlebar made of high-strength aluminum by NEKEN.
