Ok I know its an old thread but the more info the merrier. There are still plenty of these bikes about.
I have just aquired an 04 WR450f. Street legal here in New Zealand. I have just completed some basic milage testing in Kilometers. My bike has 9.8 litres capacity. 15 50 gearing for the first 80km of this trip. 15 45 for the balance.
The gearing change throws the numbers a little but this will give you the general idea.
129km to reserve, 166km to run out and another 3km by laying the bike onto its left side to get the last of the fuel to the fuel tap. At each fuel run out, the first symptom before loss of power was a few backfires before the final stumble.These were open road km with knobbly tyres.
Some mates and I are going to ride some of the high country trails in the South Island shortly. lots of gravel and shingle roads hence the knobbly tyres. if the pressure in the knobbly is around 15 Psi on the road it gets round corners like a rabid squirrel being chased by an angry dog lol. Ok so I know Knobblys arnt made for 55mph on tar seal but the experience is interesting. Safari tanks and acerbis are really expensive here. I went to super cheap and got a 5l plastic jerry can and it fits well on the small rack I got from ebay for the bike. I also got some enduro panniers, Wolf man e-12 off amazon and they are just the ticket for carrying some basic essentials without getting in the way. Fitted this week so not on the pic.
Keep up the good work on Thumper talk guys. Us older fellas need good reading material.
