Next week I will participate in what is one of Latin America's largest rallies with my WR450F. One of the time tests is comprised of 214 kilometer of beaches and dunes. There will be a tank refil point at 14O km, I have a 5L tank in addition to my 10 litre stock tank . I run a 14x44tooth gearing. Question do I have enough range with my bike? It should do aproximately 10km/liter (or 26 miles per gallon) can it do that under these conditions?
