2007 CRF450R head on 2005 CRF450X?

Recommended Posts

Blew up my 05 450X supermoto, need to do a full top and bottom end rebuild, and most likely a new head.

I'm hunting for a used, full head assembly as it would be much cheaper than piecing a new one together.

Now, R heads are much easier to find than X heads, and therefore much less expensive. What would it take to put an R head on an X?

I've searched, but can't seem to find a straightforward answer, thanks for any info!

Bike info:

05 450X in Supermoto trim

-Yosh Exhaust

-Boysen Quickshot

-Correct jetting

-Cut Air box

Appears that there will be no cons then?

Pros being better flow and a more aggressive cam?

It is the mod done to the racing X's, either by modding a X head with stage three porting and a cam, or with the R head.

The '02 R cam however is THE cam for either head.

I appreciate it, both of you. Thanks!

I keep hearing about the 2002 CRF cam, and I've been trying to look into it further.

Since my bike serves 100% street duty, I'm looking for a mid-range/top end cam, for obvious reasons.

They want $230 for a new 2002 CRF cam, $250 for a Hot Cams Stage 2. From what I've read the 02 has good bottom end, killer middle, and good top end. I've read the Hot Cam has ok bottom, killer middle, and killer top end.

I guess I'm having a hard time being convinced an old factory cam really out performs the hot cam stg 2?

I will never buy another hotcams product again.

I've had them on two of my bikes and they worked great. Why never again?
