It would be a brave individual that bought a second hand Socom now given their age. Two friends of mine (husband and wife team) ran a pair of identical Socoms for several years and they new bearings and bushes every six months. They insisted this was just normal wear and tear but I never bought that; always suggested poor frame alignment to me.
I’ve also ridden various versions of them and would agree with IA’s comments. I always found them a bit of a handful on really fast courses, scary in many ways; they need a supremely skilled rider to get the most from, largely because they pick up speed so quickly.
I’d liken them to early version of the Porsche 911; in the right hands they are supremely quick, but get it slightly wrong and it’s going to bite you very quickly and you’ll struggle to correct.
On the MTBR forum you used to see a lot of people building them up as trail bikes, I guess the pre-cursor to what we all now call ‘enduro’, but even with 160mm forks they would come out reasonably heavy and I doubt anyone would ever race one now given how light enduro bikes end up being these days.
