Engine & Exhaust
- Engine: 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.
- Crankshaft: The crankshaft on the KTM 450 SX-F is located in an ideal position close to the center of gravity, contributing to better mass centralization. It utilizes a short connecting rod, which allows for a compact motor design and a snappier power delivery. The whole unit is extremely well-balanced, with the perfect amount of inertia for optimal traction and rideability. A plain big end bearing with two force-fitted bearing shells runs directly on the crank pin, with the necessary oil feed for this bearing supplied by the engine's pressure lubrication. This design also enhances durability, allowing for long crankshaft service intervals – resulting in less effort and cost and more time spent on two wheels.
