Our most powerful air-cooled Monster is driven by the highly efficient and ultra-reliable 1000 Dual Spark engine, delivering 95 horsepower of high torque power. The 1000 DS engine was developed specifically to increase broad linear power and increase efficiency – the result is ideal for the S2R 1000. The Dual Spark solution gives a more efficient combustion and boosts power, especially at low and medium rpm, and when combined with advanced fuel injection and computer engine control, the 1000 DS never fails to thrill.
