+1 You can get maps just about anywhere but they aren't the best. Not every gsxr1000 is the same so your map really should be bike specific. Your bike could pull XX HP. Another gsxr1000 with the same exact mods could pull more/less HP.
The riders crossing the double yellow, passing in curves, etc was just plain stupid and immature. I can see taking a curve faster than the sign suggests but the rest of that shit was just irresponsible
The Busa isn't bad 2 up but I'm looking for something different for long distance 2 up riding. More than about 3 hours and the wife starts getting tired on the back
