The forged piston design of the KTM 1090 ADVENTURE, borrowed from Formula 1 technology, results in a high loading capacity, despite the extremely short and lightweight format. They are five millimeters smaller in diameter compared with those of the KTM 1290 SUPER ADVENTURE models and a whole 21 grams lighter. This reduces reciprocating weight and helps maximize the responsiveness and free-revving nature of the engine. The piston skirts have an additional state-of-the-art, Grafal® finish. Not only does this minimize friction, it is also particularly hard-wearing which makes a positive contribution to durability.
