There is a reserve to speak of but not one you can manually switch to. Basically when the fuel light comes on it´s in the reserve fuel tank mode... I ususally get approx. 50 klm.+ before pulling in for fuel when the light comes on... so it won´t leave you stranded ususally... Just out of curiousity what did you pay for the bike... I am stepping up to something bigger and mine has only got 8,400 klm on it and is mint... just wondering what they are going for a your end of the world.
