Engine & Exhaust
Engine: When maximum power is needed, there is no alternative to the stunning engine of the KTM 450 SMR. Its performance has been demonstrated in the worlds toughest competitions such as the AMA 450 Supercross World Championship and the MXGP World Championship. 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. 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.
Cylinder Head: The KTM 450 SMR 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. Low-friction chain guides further support the high RPM levels. The innovative head configuration guarantees the most efficient delivery of the unrivalled power, keeping a strong edge over the competition.
Crankshaft: The inertia produced by the crankshaft is carefully calculated to deliver optimal traction and ride-ability from the powerful 450cc plant. The crankshaft is specifically positioned to harness the rotating mass in the ideal centre of gravity resulting in a lightweight and agile handling feel. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
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 lightweight 5-speed gearbox features well-spaced gear ratios for Supermoto and is produced by Pankl Racing Systems ensuring the highest level of durability and reliability.An advanced gear sensor selects a specific engine map tailored for each gear.
Engine Management System: The state-of-the-art KEIHIN Engine Management System, with electronic fuel injection, features a 44 mm throttle body. The injector position guarantees optimal atomization of the fuel and air on the way to the combustion chamber, resulting in instant response and maximum performance when opening the throttle. There are also separate systems for cold starting and idle adjustment. The ECU features maps which have been developed to precisely match the exhaust and cylinder head, with options for regulating traction and launch control. It also provides different maps for each gear, according to the information received from the gear sensor, ensuring maximum power as you shift through the gears.
