I haven't had mine long, but it's already obvious that this is one thirsty bike. I rode side-by-side with a buddy on a 2011 Husaberg 570FE and my 2008 WR450f always drank more. One filling mine needed 1.4 gallons and his only needed 1.1 gallons.
His bike is newer, has fuel injection, may be a bit lighter, but has quite a bit larger displacement.
I don't have any other direct comparisons yet. I wonder how to help it do better ?
(btw, I had a DRZ400 and heard many folks getting 50+ mpg, while lots of folks only got around 42 mpg. I did a side-by-side with another DRZ400 and his bike got about 50 while mine got only 42, he had the FCR and I had the Mikuni. He had steeper gearing.
Also, I have an XT225 and it'll get 75 mpg while running 70+ mph, which amazes me. )
I know the WR450 is a race bike, but I'm using it as a trail bike and it would be nice to maximize the range. Any tips?
