New fzs600 rider who is heavy

[sinto607276]

I have sat on fzs600 and seems ok, for a tall guy i am actually pretty short in the leg. Also not ridden a bike in anger for about 10 years so plan is start fzs600 then possibly move up to fzs1000 once i am comfortable riding again.

In that case,
why don't you just turn up the rear shock to full, ride it for a while, get used to being back on a bike again then trade up for a FZS1000?  That way you've not spent money on a shock upgrade that you aren't going to use long term
