Help Identify Pipes Please

[JonB]

Hi, I have 2 Pro Circuit pipes I'm trying to identify. The stamped ID on one of the pipes is 89 CR 5909. This is a 125 pipe and I assume it's for a 1989 CR125. The other is stamped 86 CR 2048 and is for a 250. I assume this is for a 1986 CR250.

Thanks, Jon

So Pro Circuit wouldn't give you the info?  You DID try calling Pro Circuit, didn't you?
