2023 KTM 450 SMR
Youd be forgiven for thinking the KTM 450 SMR couldnt possibly get any better. But well 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 & EXHAUSTThe 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, youll dominate the competition apex after apex.
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.
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.
CHASSISNo matter how twisty or technical the track is, youll 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.
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.
ERGONOMICS & COMFORTThe KTM 450 SMR is equipped with a tapered handlebar made of high-strength aluminum by NEKEN. The proprietary KTM bend delivers optimal control and unintended rider impacts are absorbed by the newly designed KTM branded handlebar pad, which features the same design patterns as seen on the frame protectors and tank spoilers - now thats a touch of class.
All-new, FEA-designed footpegs offer a bigger contact area for better control of the bike while standing on the pegs, but also make them less susceptible to hooking up when leaning or sliding down low. This was achieved by a new, narrower frame mounting design.
