WR450 into 2007 YZ450 frame

6 posts in this topic

I found a complete rolling 2007 YZ450 chassis locally for $800. Just curious as to how hard it would be to swap a WR450 engine into it. I am mechanically inclined (at least my friends say I am ;), and am always up for an interesting project.

Thanks.

$800.00 seems to be a lot to pay for a frame. I have bought two- one was $550.00 delivered, the other was $350.00. They were not quite as new as a 2007 but that is a big price jump.

$800 for a complete rolling chassis is about average up here. Only things missing are the motor and exhaust , everything else is there.

Oh, that's a great price for all that!

If your just wondering about whether the motor will fit it would be easier to answer.

I can let you know if all the engine brackets fit if it helps? Sorry that I can't be of more help.

That is a good price. Forks alone are worth $300-$400 depending on condition.

in answer to the original question, it's a bolt-in IF the engine is from an '07-'11 model WR450. Earlier engines will present several problems, not the least of which is that of where to put the oil.
