Plus the Nuda motor I believe is primarily a BMW design not sure what the exact split is between Rotax and BMW . They couldn ' t really do that without paying through the nose for it . The Nuda was from when Husquavarna was still owned by BMW , so it made sense then . The big thing on those was the counterbalance system that used a long pivot arm with a weight instead of a counterbalance shaft . The counterbalance shaft design was patented , so they came up with their own design to save some cash and cut down on rotating mass a bit . Also , the FZ 07 motor has a 270 split crank and sounds fucking awesome with an Akrapovic exhaust . <| sep |> Young Man , don ' t you know , that when you get to heaven , you will be so purified from sin , so sanctified by the Holy Spirit , that you ' ll be so much more concerned about the glory of God than you will be about the wellbeing of your mother , that you will see that your mother is in hell and rejoice to know it !
