So I'm looking to get my first bike soon. I'll be taking the MSF course in probably 2 weeks. I definately want a cruiser, my choices seem to have narrowed down to Yamaha Virago or V-Star, Honda Shadow, or Suzuki Intruder. Looking at the 600-800cc range I'm 6'5", could I be too big to comfortably fit on any of these bikes? How much work would it be to make things work for my height (I have access to a small metal shop, and I'm not looking to make anything too fancy, just as long as it works.) Also, I'm ~250lbs, could that be a problem with some of these smaller engines? I plan on doing a lot of highway riding, do any of these bikes have a hard time at highway speeds? I'm not looking to be racing or anything, I just want to be able to do 65-75 without killing my bike. Any major problems/advantages with any of the bikes I listed?
