I'm not suzuki guru by any means, but I don't believe there was an 86 RMX 250. I don't think that bike came out until 89 or 90. But If i remember right it's basically an RM250 with a wide ratio tranny, enduro tuned suspension and lights anyway. Someone might have added lights and other junk to turn an 86 RM into an enduro mount and now are trying to push it off as an RMX.
