FZS600 first bike - advice?

[hobbicon]

Yes.  It depends on quite a few factors, but even a well looked after bike.  The shock at 15k miles ish will have lost its edge at least, most will have stopped damping in any predictable manner.  That said one of the factors is how and where you ride, a past it's best shock my not be noticed by you.

Thanks for the quick answer, I did not expect you to reply.
So technically I can ride on without having to upgrade the rear suspension? It's just not a great experience I guess.
