What a gem! I've got two of these little hot rods. My 1997 SLX is red as well, with full eight speed Dura Ace. What a wonderful ride it provides. As far as the serial number look on the bottom bracket shell between the cable guides. Take the number down, go to the Derosa web site, and email customer service. I received a response within two days. By the way, please ride the wheels off that thing!
