well...a "fuel empty" weight.
for example, poo w/ 12 gallons of fuel going to be heavier than nytro with 7...
thus making the numbers completely useless for comparison.
thats why when i compare weights, i look at fuel capacity, and calculate to a common capacity...usually 10 gallons...
when fuel alone is ~6.5 lbs / gal . . its going to make a difference.
but again, thats just for comparison sake...so the 7 gal nytro rider has to carry 5 gallons on the tunnel...but can weigh his sled w/o that and make it 'appear' to be lighter.
too many "weight games" being played..and I wish Yamaha didn't do it, because it just hurts their customers. Trying to find place to pack extra fuel for long / deep days...or on turbo sleds is a PITA.
but obviously companies are building "trail" sleds FIRST and mtn sleds are just an after thought.
