ok so my girl rode a ninja 250 for a year now and she is ready for a 600. im scared for her but i know she is a smart rider and wont be stupid like me. anyway what im wanting to know is how you think the f4i will suit her. she is about 5'7 130 and she is a strong chick. she could hang with girls riding 600 with her 250. also anything to look for with the f4i would help. i ride a rr so dont no to much about the f4i and diffrences

 

im 6 foot 135 pounds and it fits me perfect... ide say that ur girlfriend would be fine on a f4i its also a very comfortable sports bike

 

^Good god you're a skinny person. LOL. She'll be fine on a 600 if she's getting good and she's a good rider.

 

Well, my wife is learning to ride my f4i and she seems to do it right the only thing is the bike's height but i think that your girl could handle that issue...

 

lol yes this is true....

 

At 5'7'', unless she has long legs, you are probably going to want to look into shaving the seat down or buying lowering links. I'm 5'9'' and cant flat foot the bike even with how bald my back tire is right now. I can still get enough of my foot on the ground without feeling unstable but if I shrunk 2'' then I'd only be using 1 foot at a stand still and forget about backing it up.

 

There's one around here that's about the same size that rides an RR, street and track. I also have a buddy about the same height with an F4i that does alright, has to tip toe a bit though.

 

+1 for lowering links. it sits higher than her 250 does. besides that she should be fine.

 

I'm 6 foot, and sit on it totally comfortable, I don't even know thinking about it, if I can flat foot it. I'm sure I can ....?

 

hm.....I'm 5'7 and I can easily flatfoot the bike with both legs.
