Definitely not Tecate. Tecates have leading axle forks. the brake caliper mounts are on the opposite side of the axle boss. Also, the triples are way too narrow for 84/85. AND, KXTs used Kayaba Forks and not Showas.
My guess is 83/84 ATC250R. What ever they came off of looks to me like it has the front disc on the RIGHT side of the trike. Where as the 85 R has it on the left.
