I don't think I've ever owned a bike that wasn't a pain in the a** to fuel, but the CBR250R is a real challenge. I've gotten gas on my tank's finish so often that I now carry a disposable "wet wipe" to remove any gas that escapes the filler neck. I've also managed to find a gas station nearby where the velocity of the gas coming out of the pump is a little less than that of a fire hose and that helps a lot with eliminating spills.Yup, it’s the same for me and it was also something similar on another Honda I owned.
I can’t put the nozzle in there and fill, because it stops the pump, so I have to hold the nozzle further up. That’s made my clumsy ass spill a bit of petrol on my bike several times.
