I am looking into a crash/highway bar/engine guard (not sure which term is technically correct) for my ‘79 CM400T, and I was wondering what bikes, if any, had bars that would be interchangeable. I imagine that some of the CB models would work, but which years and engine sizes (anything larger or smaller than 450?). I am trying to avoid the really large bars as they seem un-proportionate on the bike and CM400 specific bars show up on the ‘bay’ every so often, but I’d like to expand my options if possible. Also, I found an old pair of M/C Enterprises engine guards for an 81 CM250T and was wondering if they might work. I tried contacting M/C Enterprises, but since the part has been out of production for 30 years, they no longer have any info on them. Would any of the CMX/Rebel bars work? Thanks!
