Racers can pre-register now for all rounds of the AMA Vintage Motocross National Championship Series. The seven-round series includes rounds in Ohio, Illinois, Michigan, Kentucky and Indiana. It kicks off on May 18. Links to pre-register for each round are available at www.americanmotorcyclist.com/vintagenationals.aspx.

New rounds for 2014 include Sunset Ridge MX in Walnut, Ill.; Russell Creek MX in Greensburg, Ky.; and Mammoth East in Paoli Peaks, Ind. Racers also will have additional classes to choose from, particularly expanded non-current classes.

“We learned a lot in our first year running the series,” said AMA Motocross Operational Coordinator Alex Hunter. “As a result 2014 also features an advancement system that will identify our A-class riders,” Hunter added. “We’re also going to a one-day format this year. Promoters and racers wanted a tighter program, and this makes sense for all involved.”
