XR7504 - 72/74 (LONG CIRCUT)DISC BRAKE FAIR

HarleyXR750 fairing long circuit - disc brake
The three piece design pictured was obtained from Rob Ianucci of Team Obsolete; the molds were taken off of original, unmounted Harley Davidson parts.
Two different versions are available. The lowers are similar, but the upper differs depending on whether the bike is a drum or disc brake unit.
The disc brake version of this fairing has a much smaller and shorter dash area to make room for the massive brake master cylinder mounted on the handlebars, shown in the pictures below.

XR7501 - 72/74 HOURGLASS SHORT CIRCUIT

HarleyXR750 Hourglass fairing - short circuit - low boy
This the short race circuit fairing, also known as the hourglass fairing, which was designed for use on the low boy chassis. With its much lower steering head height, this was the preferred setup on tighter tracks. The fairing itself is actually much smaller than its long circuit counterpart -- though not quite as aerodynamic. Again, these fairings were obtained from Team Obsolete and made off of uncrashed Harley parts. It you have an XR project in the works or are building a vintage racer, Airtech can make you very happy. We've got just the stuff you want.

2KR7501 - 68/69 HARLEY KR750 LOWBOY FAIRING

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.
