1984 - Armstrong of Bolton, England bought the rights to SWM Motor Works. 1987 - Harley-Davidson bought Armstrong, primarily for the rights to the Rotax engine to use for their dirt-track racing teams. 1984 - AMA approves the Wood-Rotax 560cc four-stroke single 1985 - AMA approves the Wood-Rotax 660cc four-stroke single 1987 – AMA changed the 1985 rule to No single-cylinder engine may exceed 600cc. 1988 - AMA introduces the 600cc National Series for Junior & Expert competitors on 600cc four-stroke single-cylinder engines. 1989 – AMA Grand National Championship half mile and mile events are limited to 750cc twin-cylinder four-stroke engines. The rule is a direct reaction to the growing competitiveness of the Rotax 600cc single cylinder engines, especially at half mile events. 1991 - The AMA approves the Wood-Rotax "605" - a DOHC 600cc single with dual carbs and a water-cooled head 1992 - AMA finally enforces the rule whereby only certain 600cc single-cylinder "Rotax" engines which were homologated by the Harley-Davidson Motor Company may be called "Harley-Davidson". Only Harley-Davidson factory riders may continue listing their 600cc singles as "H-D". Others use "Rotax", "ATK", "CCM", or "Wood-Rotax". 1997 – The AMA eliminated the 600cc National Series and introduces the Hot Shoe National Series as a "feeder" series to the Grand National Championship series. This series is intended to replace the 600cc National and AMA Regional series. 2002 - Single-cylinder equipment in all AMA divisions are limited to 505cc four-stroke overhead valve, 550cc push-rod engines, or 250cc two-strokes. (Had been 600cc since 1987). The odd 505cc displacement is selected based on the displacement achieved by re-sleeving 600cc Rotax engines down to near 500cc. 2004 - The Rotax four-stroke single cylinder engine which recorded wins under various names (ATK, Can-Am, Rotax, Wood-Rotax, and Harley-Davidson) scores its 52nd and final Grand National win (Chris Carr at Oak Ridge, TN short track event). 2006 - Single-cylinder equipment in all divisions (Pro-Sport all; Basic Expert & Grand National Expert Short Track & TT) limited to 450cc four-stroke engines. #flattrack https://www.instagram.com/p/Cp7zsEeOWX_/?igshid=NGJjMDIxMWI=
