Harley KRTT Lowboy fairing - short circuit
This bulbous fairing was originally designed in the Cal
Tech wind tunnel and then used by Cal Rayborn and the Wrecking
Crew. They wrought havoc on the AMA Road Racing Circuit with their
voluptuous Harley.
The fairing itself has a unique aerodynamic shape that includes
a leading edge placed extremely far forward to help keep turbulent
air attached to the very flat sides of the fairing as it flows
over it.
Through wind tunnel testing HD found that bigger
can sometimes be better from an aerodynamic perspective. This
is proven in the case of the XR750 fairing since the large windscreen
area actually helps enclose the rider completely and controls
turbulent air.
