Hi im looking at getting a yzf400 but i cant find any info on it like its dry weight and stuff!

Im thinking of getting a yz250 or a yz400 (id like a yzf450 but dad thinks it would be too much power) I just sold my 2001 yz125 which used to cain but i want more power and especially more low down power!

Thnx Simon..

Dry weight of the 400 should be in the neighborhood of 235 or so. They weigh around 255 topped off.

How big are you Simon? You may want to look at the 250F, they are atleast 25 lbs lighter and have alot more down low than what your use to.

so the yzf400 is would be heavier then a yzf450? or a 2002 crf450?

another thing is how would the 250f go in like the dunes in boggy sand? cause ive jsut started riding ther and the 125 i was just ringing its neck the whole time!

The 400 is a rock solid bike but it is heavy compared to the newer ones.

It does go good in the dunes with plenty of power. But If I were coming off a 125 and thinking 250 2-stroke or a YZ400 I would be all over the 2-stroke. For a younger person a 2-stroke is a lot of fun. The 4-strokes are fun to. But more so for the more seasoned croud (us old guys) As they dont beat you up as much.

The YZ450F isnt going to have a whole lot more power than a YZ400F and besides that, it will be easier and cheaper to get parts for the YZ450F. Also, with the YZ400F you will probably need to rebuild it very soon.

So, if your dad wont let you get a 450 I would go with the 250 smoker because the early 4 strokes are worse than the 2 strokes.

Early four strokes worse than 2 strokes, what do you mean by that?

I'd kind of like to know what you meant by that, too, especially after you said,

The difference between 43 and 49 is bigger than the numbers would suggest. You have a point about the parts, etc. but the 400 will be much cheaper to buy to begin with.

i just came up from a rm125 and i love my yz426f

you shouldnt worry about a yz426f being too fast if the yz125 is too slow

I guess I am a bit off on the hp numbers. I thought that the 400 had 46, but I guess I was wrong.

By worse, I mean that they were still slower than the 2 stroke because they were still a bit heavy and they didnt quite make the hp numbers to make up for the weight. Hearing that it only made 43hp only convinces me more that they were not quite there yet.

You will find that 43 hp from a four stroke is more usable in poor traction than 40, or 43, or 46 from a two stroke. The thumper will hook up in places that the pinger won't. Plus, the power is extremely controllable on a four-stroke. If full throttle is too much, you can dial it back and get a very predictably smaller amount as you do. If you try to do that with a two-stroke, you roll back to a certain point and it just suddenly drops off. Especially cool when you're sideways.

The only penalty was the weight. An '04 YZ250 may make 44 hp, but a 98 didn't.
