Hiya, we got my missus a 620 Monster. Not sure about different models, but be aware that the frames changed throught the years with some being the ST frame I beleive.
The one we chose was a 2003 M620Sie, because the S model that year came with an "independent ride height adjuster". They might all have those now, but I'll let someone else correct me.
Kirst is 5'2 3/4" (I know just how important that 3/4" is!), and she has the ride height adjuster down on it's lowest. Not sure if that really affects the handling .. feels fine to me when I get used to the change from the 749 to the Monnie.
Bottom line is, she can just about get her feet down enough to paddle it about. The Monster is not a lightweight bike, but carries its weight slung low (like me! hehehe) so it's not really an issue. She says she is very happy with it anyway. The bike I mean.
If you are going to be the BMF then hunt us down in the DSC tent where Kirst's "Bloo Dook" will be on display. Your good lady is welcome to sling her leg over and see if it suits her.
(love the ready for work look, btw)
