The SB6 is Bimota?s most successful model ever, with over 1300 units sold worldwide. This is the kind of bike for you if you crave something exotic - but love the screaming rush of a 4-cylinder more than the softer delivery of a twin. The twin exhausts exit from under the seat, which makes for a great looking rear end on the bike, while giving you a very hot rear end, and that doesn?t mean a good looking bum either.
