Seems pretty reasonable. Make sure it has good compression and that there is no free play in the head stem, linkage, swingarm etc. Make sure the fork seals are not leaking and make sure that the bike runs good and strong. The last thing you want is a old bike what needs over 1k just to make it safe to ride. The older CR125s from the early 90s to 97 had a very good strong motor but they handle like crap and have crazy death shake/death wobbles what ever you want to call it.
