You don't go fishing in a tuxedo, and you don't wear waders to a wedding. Two different bikes for two different riding styles. Given riders of equal weight and skill I think its gonna be hard pressed to call a winner on any given day up to 175mph. Beyond that ...well thats BUSA TERRITORY!
But hey how often you gonna hit those speeds on your daily commute???
Decide whether or not comfort, power, and being able to honestly say you have the fastest production motorcycle in the world is what you want. If so buy a BUSA!
OR if you want to say you got the the fastest corner carving machine ever to leave japan, and ONE OF the fastest bikes in the world, even though it aint that comfy buy the 1000..
Bottom line you gotta ride the bike that calls to your spirit and meets your needs whether its a BUSA or a KTM.
Remember its not what you, but that you ride ...thats my $.02, now keep the shiney side up
