At around 160 the 12 should start pulling the 10 on aerodynamics alone.The 12 was built in a wind tunnel and has lower drag numbers than the 10 which was designed as a track bike that has good aero but not like the 12.That was the one thing the Busa had on the 12 was better drag numbers.2000-2001 had almost exact hp as Busa and weighed less but was not as fast,the reason,aero.In 02 kawi tweaked the front and gave it a few more ponies and since then it has been faster than the busa in top end runs to the resricted 186.
