Why John Dowd is on this page

Heritage: Dowd-surname carrier in American motocross; no documented Irish ancestry in the cited Wikipedia article. Heritage classification: surname-carrier.

John Dowd (born 1965) is an American professional motocross and supercross racer from New England — celebrated within the AMA scene as one of the great sand-track specialists, a particular mastery suited to the strength-sapping, deep-sand circuits like the historic Southwick National in Massachusetts. Notable late-career performance: in 2005, days short of his fortieth birthday, Dowd finished on the podium in third place at the 250cc Southwick National aboard a privateer Suzuki RM-Z450 — an exceptional result given his age and privateer status against full-factory teams. He is one of the small group of John Dowds in this batch who require parenthetical disambiguation in their slugs.
