I want to replace the rear shock on my 250R. I will probably stay with a original Honda shock but my question is will the shock off of a 87-89 TRX fit my '85 250R. I would have to guess that Honda must have changed something on a 1989 shock to make it better than a 1985 shock. I just want to know about shock length and mounting. Please dont fill me with useless "I guess" or "I Think" replys Who really knows.........
