I'm tall and the build of the Spyder seat in relation to the foot pegs and foot brake pushes me a bit too much forward---I think being 5'3" would be about perfect for sitting on and operating the Spyder SE5, which is what I have. I installed the 4" risers that can be found on Ebay (Can Am Spyder), and they are really nice and adjustible--they go up and pull back toward you allowing you to make it fit your reach and size. The original windshield is too small----so if you get an F1 Winshield from Marcel in Florida, it's perfect. Being older, I had to get rid of my motorcycles---can't handle the weight, unsteadyness, and putting the feel up and down constantly---so the Spyder is doing fine right now---I've had it in water,dirt, and slight gravel, and it did fine---just didn't push it too hard. The Spyder is a realtive new machine with some correctibles/mods/and changes---it has the potential of being not only a great looking and great operating machine, it could end up being one of the best "open-air" rides in the world. When the weather improves and the rains end, I'm taking my red and black Spyder (The Black Widow) up the coast of California for a long and tough ride---will push it to its limits---if it makes it, I'll be happy---if it breaks up, I'll see where it goes from there----The SE5 (electric shifts) have had some issues (problems)-----So----as was said, take a good ride and see how it fits----good luck.
