KX250 Chassis With 500 Motor

Looks likes you got some fun work to do

Hi, I joined the forum specifically to find this information, as I don't even own a Kx500.....yet. I just want something different, the 4-strokes leave me cold, and My CR500 needs a bunch of chassis work to handle anything like the new bikes, plus, it's a Honda, blargh.

So, a 2004+ Kx250 with a 500 transplant is just the thing. Like cyclepsych0, I'm hoping that like the posts don46 made for the 99-02 bikes, someone can fill me in on the steps necessary for the newer generation.

Thanks in advance!

Yeah, Sorry, I've given up on the 250 chassis, I've got a steel 250f and the AL 450f chassis. I'm sure it wouldn't be a big deal to use the newer 250 chassis, just not my thing now.

How does your 250f frame hold up with the power of the K-5 engine???
I have a 04 RMZ 250 and just love the way it handels.

I think I like the 250f steelie better than the aluminum framed bike, but to be fair I've had some time to dial the 250f in and not the aluminum bike and it has an Ohlins rear shock that works wonders. If you did the conversion you wouldn't be disappointed, it really feels narrow and light almost like riding a 125, seriously.

With a aluminum frame there is more matriale of the frame it self to use for welding than the steel frame.
But I think that I would go for a 250f subframe and weld a alu thank at work.
?hlins works wonders on the suspension!! As you can see on my picture there's ?hlins shock and 48mm forks on    They make the woops disappear
