I finally took the plunge...I have always ridden and raced YZ's but have had XR's for off road and dual sport. I just bought a new 2005 WR450. This bike will be used for big long rides in the middle of nowhere (western deserts, Baja, and Dual Sport). I see that Acerbis makes a 6.6 gallon tank for the bike. I have not had the best of luck with the Acerbis tanks on XR's and am a little hesitant to buy this for the WR, but no one make a tank over 4 gallons (3.3 gallons for that matter, it seems). Does anyone have experience with this 6.6 gallon tank?
