Brough Superior Front Fork, showing dampner…. Interesting the same type of dampner used on the 1928 Harley board tracker….Known as a Castle Fork, this type of springer was used by a number of bike manufacturers over the years…Harley riders just called ’em “springers”…

Many Thanks to Professor George Hood for identifying this type of ride control and
knowing that Brough Superior used it on some of their road bikes.. The “Castle” fork
has been credited to Harley as the originators of this fork….Not really true… Ain’t
life strange? This type of dampner, as shown on the Harley board tracker used huge
bearings on the rockers….I’ll bet the designer was trying to get all the stability
he could….. Springer forks with loose rocker bearings have a tendency to allow
a deadly wobble to develop at speeds over 80 mph….
