A few years ago I saw an article in one of the main dirt bike mags where a company outfited an aluminum framed CR250R with a kit that allowed the frame to be filled with fuel. Also, they made a skid plate that utilized the area below the engine cases and between the frame rails to carry more fuel. It sounded kinda like a wacky idea, but if it woks out ok, it would be nice to gain the extra fuel capacity without having to resort to a oversize tank which seems to ruin the nice egros of the CR. I dont have the mag anymore and do not remember the name of the company. If anyone has any info I would greatly appreciate it.
thanks
