You have to be kidding so this is a joke right?
If not then look at the info on the Honda site of the two bikes along with the info.
One is a V-twin of 1000cc & the other is a four in line of 600cc. First was designed to be competitive to Ducati V-twin 1000cc bikes in road racing only that is not needed with changes by the FIM. The 600 is the street version of their 600 road racer.
Remember all the others on the road are crazy & out to kill you.
