Ratz Racing has these in Ventura, they also have the upc pro, and today they told me that the new upc pro now comes with the Elka rear shock. That shock is a big improvment over the one one the ThumpStar and the UPC. One of the owners at Ratz told me that the forks on the pro are not any better than the reg. 125 forks. ??? THEY take one of the 125 pro's to the piru track every wed. and have not had any problems as of yet.
