In fact, I'm hoping that Kawasaki does this exact same mod and calls it the KDX250F.
The picture was taken from the December Dirt Rider Magazine. Kawasaki was displaying this bike and a KX250 in SuperMotard trim at the 61st Milan Motorcycle Exhibition. New EPA standards go into effect in 2006. My guess is the four stroke will meet emission standards easier than a two stroke. Even so expect the four stroke model to de tuned to meet the new emission/noise standards. Expect the KDX line to disappear from the USA soon.BPJNT said:Where did you find that picture?
What do you know that the rest of us don't, looks like an awesome bike in the pic. Give us some details. Is it just a KXF with a light or is there more?

coleman said:230 is a little heavy for a 250 four stroke but if you're riding a kdx at 230 then you will have no problems with a 250f. I used to have a kdx and I switched to a 2001 yz250f. Really glad I switched. The 250f has way more power than my kdx ever had plus the suspension, brakes and ergos are much better.
rv6junkie said:You can extrapolate the torque curve by taking the HP number, multiplying it by 5252 and then dividing the result by the RPM.
Generally speaking, the four strokes have more area under the HP curve, a clear indication that they are making great torque. For example, two engines (a 2-stroke and a 4-stroke) make the same 30 HP peak HP. The 2-stroke makes 90% of its peak between 7,000 and 9,000 rpm but the 4-stroke makes 90% of its HP between 5,000 and 11,000. This greater area under the curve is due to a torque curve that reaches its maximum value early in the rpm range and is able to sustain that value for a considerable period of its rpm range.

The 1 piece waterpump and oil filter cover has a reason according to kawasaki. The filter will last the life of the top end. So when you change the top end after 3 rides, you will drain the coolant at the same time.
This is direct from Kawasaki.

That filter design sounds wack! Well no suprise as it's a POS Suzuki with green plastic...
NYkdxer said:gwh, I'd suggest you read "Two-Stroke Tuner's Handbook", by Gordon Jennings. It's aimed at the two-stroke enthusiast and may help answer your questions. I got it out from the local library and haven't finished reading, but its a great text so far. Very in-depth, which i like :)
