Looking for a dirt bike

[scapco at ecentral.com]

If anyone knows of a clean used "titled" dirt bike for 
sale, I am looking for one reasonably close to Colorado.

I've been looking for something like a KLX-300, DR400Z, 
CR450X, YZ450WR, etc..  It has to be titled so it can be 
licensed in Colorado.  I intend to use it for riding 
mnountain trails and passes, and will keep my KX250 for the 
track.

Thanks,

Charles
