hi, i own a 2005 yamaha roadstar midnight 1700 and my brother has a 2006 yamaha stratoliner (same as roadliner but with bags and some) the roadliner has a 1900cc engine while the roadstar has a 1700cc engine and is fuel injected for the 2009 model year. i stand at 5'9" tall and weigh 235 lbs and i think that the roadliner is too wide for me. i think the best thing to do is to go to a dealer and sit on each bike and if possible test ride them. i love my roadstar and it's not a small bike, but very powerful also. good luck on your new toy.
