to be honest I don't know all the technical stuff but I can tell you it pulls like a Mac truck EVERYWHERE. The bike feels violent at anything over 6k rpms. I jump on a 03 gix 1000 and it feels like a 600 compared to this monster.
a complete blast to ride and it wheelies at will through 4th and just a little extra and it comes up in 5th with no problems.
