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 & EXHAUST

• 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.
