Dude. they look terrible. No offense.
Doesn't the 250R tank fit under stock plastics?
I maxed the tank out last trip. Wash 19 to Brawley Slide, then out to almost roadrunner, back around to Brawley, over to Gecko Loop, out to Olds then to the drags. I hit reserve leaving the drags. Made it to Olds road from Sand Highway before the reserve cut out.
So, a stock tank aint too bad.
