So ever since the catalyst came out I've been really hoping there going to figure out a way to drop a four-stroke in there and update the ZR9000... But after reading this article I don't think that's going to be a possibility...

"Because of our direction at that time, the [ProCross/ProClimb] chassis was built to be able to house pretty much any engine [two-stroke and four-stroke] that we could come up with. There was always the dream or the hope to make a dedicated two-stroke chassis that is tight and right, and everything is built around just those engines. With the Catalyst, that was the plan – make it right for our two-stroke engines and make a platform that is much improved in many ways."
