New 2024 KTM 450SX-F

Youd be forgiven for thinking the KTM 450 SMR couldnt possibly get any better. But well let that slide - just as youll be doing when you throw a leg over this latest iteration of pure Supermoto 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, youll dominate the competition apex after apex.

• Cylinder head

A compact and lightweight SOHC cylinder head package uses a short profile with the camshaft located close to the center of gravity, improving handling. 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. Optimized intake ports allow higher flow coefficients, resulting in a more efficient and powerful engine, with a clever valve cover reducing the number of mounting screws, and a single oil spray jet guaranteeing efficient cooling while keeping the weight low.

CHASSIS

• Frame

No matter how twisty or technical the track is, youll stay in control thanks to a frame design that has not only been engineered for optimal longitudinal rigidity but also positions rotating mass as close to the center of gravity as possible. Precise frame wall thicknesses deliver superior flex characteristics and offers an unmatched rider feel. The shock mounting also provides optimal anti-squat behavior to better drive out of corners.

• 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.

ERGONOMICS & COMFORT

• Handlebar

The 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 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.

• Footpegs

The 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 narrow frame mounting design.

• Seat

A flat seat profile and high-grip orange seat cover provide exceptional rider movement and control, with a handy grip pocket under the seat, just above the air filter box, making lifting the bike off its paddock stand a lot easier.
