02 YZ250 217 lbs (2 stroke)
02 YZ250F N/A - 03 208 lbs
02 WR250F (unofficially 234 lbs from dealer/tech)
03 WR250F N/A, but is supposed to be lighter!
02 YZ426F 230 lbs - 03 YZ450F 222 lbs
The literature is boasting a 10+ lbs saving (probably from the sales people), but as we can see, it's only 8 lbs according to the specs (probably written from engineering).
02 WR426F 240 lbs - 03 WR450F is supposed to be lighter even with the magic button according to the literature - they did a lot of weight trimming and suspension tuning for the 03.
Other noticeable 03 WR450F improvements (from memory): From the literature/picture, it looks like the air filter is accessable from the left side now with no tools - this is good for people who keeps the cap on and potentially bad for those who takes the air cap off since it is closer to the elements. The kick start has automatic compression release. The hot-start compression release is a lever on the handle bar and the clutch has the big easy-adjuster while the brake is also easily adjustable. The header & pipe are titanium and the muffler is stainless steel. Engine components are lighter. Brakes are new/stronger and lighter (the rear brake's remote oil resevoir is gone). Engine protective walls are thinner/lighter. The skid/engine protective plates are now half plastic and half aluminum (more weight saving) - and of course everyone's favorite, the electric starter (this will make it easier to convert to street if need be since it now has a battery).
If the YZ426F went from 230 to 222 lbs, I'm hoping the WR426->450F will have a similar weight loss.
For wet weight, lets say 1 gal = ~8lbs + oil + antifreeze = roughly ~25-30 lbs for a 2 gal tank.
03 WR450F on order - I can live with ~270 lbs wet!
