Ok I have a 89 RM250 and she is really thirsty compared to my friend's crf250x and I'd like to increase my range. Did the RMX have a larger tank than the RM? How much larger? I can get a 4.7gal tank that fits my bike, but that is just too much added weight to slosh around. There is a 3.4gal tank for the newer RMs that I could make fit, but then I have to also buy the matching radiator shrouds. Or i was thinking of buying a couple of those Stainless steel water bottles and carrying one in my camel back and another in my fender pack. Im hoping the RMX tank is larger because I'm eyeing one up So what would you guys do?
