Not mine, saw it and thought some folks here might be interested in a pretty clean '89 GSXR 750: https://sandiego.craigslist.org/csd/mpo/7561804512.html Generally looks good, see some oxidation on the triples, but otherwise looks well cared for.
Thanks for posting. Lots of good memories from that era. For what it's worth, it looks to me like a 1990 or maybe an '89 with '90 bodywork and tank.
