Hey folks. I know you have discussed gas mileage for the 2 strokes on occasion. I currently have a 2017 500 RR-S and put the 4g IMS tank on it just to make sure I have the range for trips. I rarely fill it all the way, but I can if I need to. I am now considering getting either a 2018 300RR or a Xtrainer more for my local rides in the Cloudcroft area of NM (most rides from 7000-9500 ft). I know that I can get the 4g for the 300RR, but it looks like there is only a 3g IMS tank for the Xtrainer. My understanding is that fuel mpg for these carburated 2 strokes can be on the order of the low 20's. I am 61 and have reasonable skills. But often ride alone and therefore ride very cautiously in these rocky trails to minimize chances of a fall where I get stranded (do carry an inreach just in case). Do any of you know whether the 2018 versions have any improvements in gas mileage and what mpg I might expect for my riding style and conditions? There are some rides here where I need to get around 60-70 mi round trip from a gas station. half of that would be on a paved road with potentially better mileage. I know I can add the 4g to the 300 and should be able to make it, but it looks like there is no option for the Xtrainer. I have read many reviews of the new FI 2 strokes and know there are many opinions that the carburated bikes are better. But I have to admit that I am tempted simply for the 30-40% improvement in fuel mileage. Many thanks for your thoughts.
