It's a clear tank for F#$K sake put 30lts in it ride it till the fuel light comes on and you have got 5lts left which equates to about 50k's or when you can't see much fuel in it it's probley about to STOP don't worry about an extra 15 kilo's of fuel fill it up and ride it. I hope this has been of some help "Run out of Gasman" Cheers Emu
