2012 KTM 500 EXC is packed with perfectly controllable power in extravagant proportions, low weight, and an unsurpassed chassis, characterizing an enduro of remarkable versatility. For the 2012 model, the 500 EXC has a new 500cc 1-cylinder 4-stroke, water-cooled engine that has been redesigned from scratch and is now more compact, lighter, and more powerful than before.
The 500 EXC’s cylinder has been further developed especially for the new engine configuration. The new, 15 % lighter forged piston minimises reciprocating weight and optimises durability at high engine speeds. New, nitrided piston rings ensure highest levels of resistance to wear. The engine has also been equipped with a common oil circuit for engine and transmission, and two oil pumps. A pressure pump lubricates the engine, while a suction pump draws oil from the crankcase, using it to lubricate the transmission and the clutch.
