Yamaha Royal Star Tour Deluxe for 5'7"?

Hello there, I am trying get a bigger bike, and seriously considering Yamaha Royal Star Tour Deluxe. I know that visiting a local Yamy dealer is the best way to go for this type of question, but I am kind of far a away from visiting one occasionally. As stated, I am 5'7", when I seat on a Honda VTX 1300R, I can plant my feet completely on the ground, but can't if I seat on VTX 1800R. I know this is due to my leg length and how wide the seat for VTX1800 is made, but I think I can manage those bikes at the 1300cc range to 1500cc, including VTX1300R, Vstar 1300 and Suzuki C90T. By the way, I know that the Royal Star Tour deluxe is about 100 pounds heavier than other 1300cc models. Thanks guys.
