Engine & Exhaust
Engine: The 450 cc engine is the ultimate powerhouse when it comes to KTMs competitive motocross range. Its compact, lightweight design features a single overhead camshaft cylinder head, fueled by a highly advanced 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 FACTORY EDITION 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 intake side are DLC coated, allowing for impressive engine speeds up to 11,500 rpm. The innovative head configuration guarantees the most efficient delivery of the unrivalled power, keeping a strong edge over the competition.
Crankshaft: The crankshaft on the KTM 450 SX-F FACTORY EDITION 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 ride-ability. 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 engines 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.
Crankcases And Engine Covers: The compact engine cases are manufactured using a high pressure die-cast production process that helps with weight reduction, while retaining strength and durability. The design allows for optimal shaft arrangements close to the center of gravity, resulting in better mass centralization and easier ride-ability. The engine covers feature a smart surface structure that reduces wear caused by the riders boots, keeping them looking as fresh as the day you bought it.
Transmission: The transmission on the KTM 450 SX-F FACTORY EDITION is focused on lightweight performance without compromise to durability. The gear ratios have been perfectly matched to the power delivery of the large displacement engine. The engine is fitted with a gear sensor, which provides the option of different engine characteristics for each gear depending on engine load. An advanced no-dirt gear lever design prevents dirt from building up and together with the reliable gearbox, guarantees that the next gear is always an easy click away.
