I think Im right in thinking that the 1098 holds 17lt of fuel. When I fill the bike to the brim and then ride I get the fuel light comes on around 89/99 miles, when I then fill it again I can only get about 9lt in it, does this mean that I have approx 8lt on reserve. does this sound right??? is this what everyone else is getting??? If so isn't this a lot of fuel on the reserve
