Since you have two answers giving the same figure of 238 with cited sources, I don't know why you would give any credence to the gratuitous assertion that "those bikes weighed 250 pounds".

The '99 owners manual lists the weight with oil and a full fuel tank as 252. If you subtract 16 pounds for fuel and oil, an estimate, you get 236. Sounds like that's the answer.

Remember that dry weight means dry; no fluid in anything, even the rear shock.

I go off what I read in dirtbike magazine. If you believe your manual than a new 450 is under 220. I think not.

The question was about the dry weight, and the dry weight of a new 450 IS under 220, as it has been since '03.

Dry weight is only really meaningful if you intend to run in the soapbox derby, though.

I had a 99 400 and I weighed it one day at work just to see what it really weighed. With half of a tank (1 gallon) of fuel and all other fluids serviced and a set of barkbusters on it, it weighed 252 lbs. My buddy's KTM 400 weighed a pound or so under 240 lbs. I would say that Gray man is pretty darn close with his math.

Since were talking about the prune and not the plumb, I'll have to agree with older & yzer

I have a 99 YZ400, and went to some lengths to lighten it up. I'm a mechanic and never get tired of just modifying/playing with bikes.
I have weighed it throughout its life.
It started out at 248 pounds, all fluids but no gas.
Got it down to 234, still all fluids but no gas, with a dry sump still in place. Could have peeled off another four or five pounds maybe. But I wandered off to another project!

I'm curious how you lost that much weight on a YZ400 and how much it cost. I'm not doubting you because I know it can be done, but it usually cost some serious coin to do it.

I personally think eliminating the dry sump on the YZF pretty much limits you to an hours worth of riding at one time and makes the very one dimensional. I know the pro MX'rs do it, but for the other 99% of us, it doesn't seem to make much sense. Just my opinion of course...

Are these bikes also way top heavy? I've always wondered how heavy my bike would feel compared to a new thumper.

The Dry weight is 231LBS


Same dry weight as the 00 426F. I have looked at ways to shave weight on my ole 426 and found the easiest way was for me to drop some lbs myself. I dropped 23+ lbs and it now feels and handles much much better. Hell I just upgraded to a 450 weight wise and didn't have to spend any $$'s :thumbsup: Okay, not really...
