The innovative head configuration guarantees the most efficient delivery of the unrivalled power, keeping a strong edge over the competition. Low-friction chain guides further support the high RPM levels. The rockers on intake side are DLC coated, allowing for impressive engine speeds up to 11,500 rpm. The four ultra-lightweight titanium valves (intake 40 mm, exhaust 33 mm) are activated via extremely rigid rocker arms. The overhead camshaft has a friction-optimized surface and valve timing that delivers impressive responsiveness. The design focusses on mass centralization, contributing to overall handling excellence.

Cylinder Head: The KTM 450 SMR is fitted with a lightweight, compact SOHC (single overhead camshaft) cylinder head.

Mass-centralisation is key in the engine design, enabling chassis engineers to position the engine closer to the centre of gravity for great handling and manoeuvrability. The SOHC power plant is the perfect example of the advanced engineering techniques offering a peak power at an overall weight of just 27.3 kg. It's performance has been demonstrated in the world's toughest competitions such as the AMA 450 Supercross World Championship and the MXGP World Championship.

Engine: When maximum power is needed, there is no alternative to the stunning engine of the KTM 450 SMR.
