Bake has made a 1.1 gal aux fuel tank for the '09 KLX250. I'd seen the ones he made for the '07 models, but this is new just for the '09.
I'd imagine he'll be selling them in Flea Market soon.
Yes, this is probably
but I've read here that many of you seem to be looking for a "more fuel, longer range" option. Thought I'd let you know about this.
