Hacking, Yates and DiSalvo lead the way in Repsol Lubricants Superstock. The typical pattern in the Lockhart-Phillips USA Formula Xtreme Series is for two riders to separate from the pack and have a great battle for the title. The last few seasons it was Miguel Duhamel and Jake Zemke taking the championship to the wire. Before them it was Jason Pridmore versus Zemke, or John Hopkins vs. Damon Buckmaster and so on. While it’s certainly early in the year, the 2006 series seems to be taking on a familiar tone as Yamaha’s Jason DiSalvo and Josh Hayes, of Erion Honda, emerge as the title contenders. The series moves to California Speedway on Saturday, April 29, for round three.
