The FZR and ZXR were both sold officially in the UK at some point and so parts are easier to locate.

Regardless of how good these things are (a mate had a VFR400 in the mid 90s), most are now getting on. They were also often owned by novices who thrashed them unmercilessly. In the 90s when insuranced worked differently (much more on CC than outright statistical risk), they were popular due to the high performance but low insurance cost - this may not hold so true now, as insurance companies know that they are likely to be written-off easily as parts are scarce/expensive.

Nothing wrong with a good one - many are getting sought-after/collectable, but for a fixer-upper with plenty of parts on fleabay, you are far better off with an early noughties 600/750 for the same money.
