Featured In the August 2024 issue of Roadracing World:
This story starts in a small town of Bellshill in Scotland where Norton engine wizard Joe Potts, engine fitter Pim Fleming, fabricator Alec Crummie, and gifted rider Bob McIntyre (the first rider to average over 100 mph on a lap of the Isle of Man TT course) had their headquarters.
McIntyre’s ideas as to how aging British Singles could be made more competitive centered around weight reduction and improved handling. Potts concentrated on engine preparation and modifications using his Heenen Froude engine dyno.
In 1961 McIntyre and Crummie designed a special lightweight frame to carry a 500cc Matchless G50 (see May 2014 issue of Roadracing World) or 350cc AJS 7R engine and Norton transmission. Although a standard G50 made less power than a 500cc Manx Norton, it was lighter and Potts felt he could squeeze some extra power from it…

Bob McIntyre’s career was tragically cut short by an accident at Oulton Park circuit in August 1962, from which he died nine days later. But this was not the end of the McIntyre G50.
