I had an srad 600, mrs hated being on the back of it, now have an r6 5eb, and she says it's soooo much more comfy, also added some anti slip netting over her seat for a little more support. As for her getting on as pillion, she just throws her leg straight over and hops on, doesn't use my pegs or anything.
We also use pillion buddy handles which she swears by.
