I rode the supersport 1000DS last year with this engine, I believe that the engine is put to far greater use in the monster. I love the relative unfussy mechanics of the lump compared to the testastretta, and the way it gets up and goes, and oh boy it went.... just wish i could have put it on the track yesterday, but being a courtesy bike, i dont think they would have been too impressed if i had returned it with threadbare tyres
