Nothing whatsoever.
I have a 1992 Yamaha FZR 1000 Exup RU.
Since I bought this bike, I have made many modifications which include 2002 R1 Calipers, and 16/48 Gearing.
This bike is awesome!
My brother has a Thunderace and I can reel him in under power each and every time, I also raced a 2002 CBR 954 RR FireBlade and he couldn't pull away from me either.

I agree with you, when well looked after they can keep up with most new kit, maybe I think the upgrade on brakes is a good idea as this can happen.

Easier to ride fast than a GSXR, they corner like they`re on rails without having to climb all over the bike. I loved mine, but it was boring unless you had someone to race all the time. Unless you were doing at least 120+ round the corners, there was no skill or effort needed : (. I then bought a DR Big 800, if you went round a corner at 80 mph, whilst trying to hold it steady, you felt that you had achieved something LOL.
