I hit 49 mpg twice. My son says I must be a poser.I know this about the 2008 Busa, but I just had to chime in. 2005 Busa, all stock except for TRE, 44 miles to the gallon commuting to and from work. Long trips yeild as much as 49 mpg.
Not for some folks, they are not. For some, they are much more serious than a toy. MUCH more. For example, I haven't owned a car since 1996. Motorcycles are my sole means of transportation.... admittedly, some years, winter is less than fun. But I manage.Most motorcycles are more like an RV or a boat. They are a toy.
Concur, it's probably very, very small.(of course I'm talking about the United States) I think if you look carefully you will find most motorcycle owners have a 4 wheel vehicle. I'd even step out further to say the percentage of Busa owners that use it as their sole means of transportation is very, very small.
