ENGINE & EXHAUSTUnrivalled power
The 450 cc engine is the ultimate powerhouse when it comes to KTM's competitive motocross range. Its compact, lightweight design features a single overhead camshaft cylinder head, fueled by the latest electronic injection system. This enables the impressive power to be distributed extremely efficiently throughout the rev range. Even with its super-beneficial electric starter, this model is still the lightest 450 cc engine on the MX market.
- CYLINDER HEAD
The KTM 450 SX-F is fitted with a lightweight, compact SOHC (single overhead camshaft) cylinder head. The design focusses on mass centralization, contributing to overall handling excellence. The overhead camshaft has a friction-optimized surface and valve timing that delivers impressive responsiveness. The four ultra-lightweight titanium valves (intake 40 mm, exhaust 33 mm) are activated via extremely rigid rocker arms. The rockers on the intake side are DLC coated, allowing for impressive engine speeds to 11,500 rpm. Low-friction chain guides further support the high RPM levels. The innovative head configuration guarantees the most efficient delivery of the unrivalled power, maintaining a strong edge over the competition.
CHASSISSuperior core stability
As with the entire KTM SX range, the frame on the KTM 450 SX-F is professionally crafted from hydroformed chromium molybdenum steel tubes that are robot welded to ensure the highest levels of consistent quality. The precisely calculated stiffness of the frame delivers responsive handling and works perfectly with the suspension to provide excellent agility and high-speed stability. All 2020 KTM SX frames feature a highly durable powder coating and come with standard frame protectors. The subframe is made from lightweight aluminum and provides great feeling for the rider, as well as easy movement across the seat.
The KTM 450 SX-F's one-piece swingarm is manufactured using a gravity die-cast production process for exceptional strength at the lowest possible weight. It offers a wide range of adjustment for the rear wheel, allowing for a shorter wheelbase on tighter, twisty tracks, or a longer wheel
