Ihave been reading the board for about 6 months. It was a big factor in my buying a new busa in Feb. The bike is great have already put 2000 mi. in it. I use it for daily commuting, which is about 120 mi. a day. How may miles can I expect to put no it before it has major problems. If all the maintance is keep up. Put 40000 mi on my last bike. This bike sure does make the commute go by quick.
