Hi from Cairns

Hi guys and girls.
My names Luke, 18, live in Cairns QLD.
Tomorrow I will hopefully give the nod to a 2007 GPX250. The bike is cheap, has rwc/registration, service history and has been owned by a 60 year old from new (im not kidding). Only catch is it has done 47000 k's
So my first question is what are the common problems if any with the later model gpx and what should i look for? Appart from the obvious like chain and sprokets etc. Also how many k's could you expect from a well serviced 250 before it would require 'freshening up'.
Thanks and ride safe.
Luke
