Harley-Davidson has slashed its AMA Pro dirt track support programs for 2010, ending support for “Wrecking Crew” riders Joe Kopp, Bryan Smith and new National Twins Class Champion Jared Mees. Harley-Davidson will continue to support Ken Coolbeth, the official team rider whose equipment is prepared in the factory race shop. Harley-Davidson dealers running programs for Mees, Kopp and Smith were informed of the cuts yesterday.
