Hey check out this video and see if you recognize the sound of the lead bike taking the video! Sounds like an SV to me. I know some of you are probably going to flame me and say that it's not, but it has to be. You know how the V-Twin sound deep at low RPM, then it get's into...not so good sounding scream at high RPMs.
Those guys are crazy too...look how close they are riding together. What if one bike crashes...he's gonna take other down with him. WAY too close for comfort.
