My girlfriend is 5'2" and currently rides a 14 plate ER6F that has been lowered and has a dipped seat (I'm not happy with either job, but its not my bike). She is looking to swap and doesn't know what to get that can be lowered for her etc. She wants to do some touring, blasts out with me and others and the odd commute to work. The ER6 doesn’t have enough grunt so she is looking for something with more power. She doesn't like the riding position of my RR5 as its too far to stretch her little arms to the bars but saying that she hasn’t ridden it only sat on it in the garage. We went to look at a MV Dragster in a local garage and she loves the look, size and weight of it but I'm slightly apprehensive about reliability and supply of spares and it’s at the top end of her budget too at £8k. Off to bike show in Nov so will hopefully be able to look at plenty of options but most brand new models will be out of her price range. Feel free to suggest any models that fit the criteria.
Girl comes out with us has a K2 6OO quick google and seat ht is 830 and shes small the L1-L6 IS 810 and lighter so try her on 1 of those try her with some heeled boots as well.
It's not all about the seat height. The wife is a short arse, and whilst her legs are longer than mine she can't get her feet down on bikes that I can due to the width of the seat. It really is a case of time spent sitting on bikes, what a shame that is
