cc50= Coast to Coast in under 50hrs. It has nothing to do with what size m/c you ride to do it. Go ahead and take your 1800ish bike. I know people that have done it on their Honda Runes. (not me) But I did do 1/4th of a 1000 IB yesterday on my Gen II. I hope I don't get any 'surprises' in the mail within the next week or so because of it. lol
