Ok to start with the bike is a vf400 integra. I have 2 problems with this bike that I'm hoping I can cure in one go.
Firstly , the bike is for a girl who is on the short side shall we say
Secondly the shock is knackered ( I think)

So what I was proposing was using a slightly shorter shock of a later bike. Now I'm hoping that due to her weighing less than a bag of crisps the later shock ( designed for a lighter bike) should still be ok.

Ideally I would get a hagon or something where they use a spring suited to her weight but budget don't allow this.
Can anyone point out any problems with this cure ?

Cheers
