The Insane 70° Engine Layout Nobody Had the Guts to Copy

Every four-stroke motocross engine faces the exact same enemy: cylinder height and gyroscopic crank torque fighting you in every corner. In 2009, Husaberg solved this problem with an engineering move so aggressive no other manufacturer dared to copy it: they laid the cylinder 70 degrees forward, nearly on its face. By rotating the engine forward, Husaberg relocated the spinning crankshaft 100mm higher and 160mm rearward—placing its rotating mass right at the motorcycle's natural pivot point. The result was a bike that flicked into ruts with virtually zero gyroscopic resistance. But rotating an engine 70 degrees created a massive cascade of engineering headaches: upside-down intake ports, custom dual-pump oiling systems, backwards exhaust headers, and split gas tanks. In this video, we break down the mechanical genius behind Husaberg’s 70° tilted cylinder, how it solved four-stroke handling physics, and why KTM ultimately let the concept die when they absorbed the brand.
