Are we talking stock bike here? (Keep in mind that I'm still running-in a 1 week old bike so I'm may be completely full of sh*t)
One of your yankee miles equates to 1.61 of our aussie kilometres - so, if the Rocket can theoretically hit 239mph that equals 385km/h??? At 3000rpm my beastie does 120km/h so at 6000 theory is she'll do about 240km/h depending on wind/fuel etc? that equals 139mph.
Someone tell me I'm missing something here before I send my bike back to the shop to find my extra 100mph!!
