Klock Werks Billboard Flare Windshield For Harley Sportster / Dyna 1988-2022

Klock Werks Billboard Flare™ Windshield: Aerodynamic Excellence for Sportsters and Dynas

Transform your cruiser into a high-speed touring machine with the Klock Werks Billboard Flare™ Windshield. Specifically engineered for 1988–2022 Harley-Davidson Sportster and Dyna models, this shield is designed to replace the standard flat glass on “King” style detachable windshield assemblies. The Billboard Flare™ isn’t just a piece of plastic; it is a performance-driven aerodynamic tool born on the Bonneville Salt Flats. By applying patented fluid dynamics to the classic cruiser profile, Klock Werks has created a shield that makes your Sportster or Dyna feel more planted while providing a much quieter “air pocket” for the rider.

Patented Aero Design: Hips and Flip Technology

The Klock Werks Billboard Flare™ stands apart from traditional windshields due to its innovative shape. The “hips” on the outer edges of the shield act as miniature spoilers, catching the air and pushing it outward while creating downforce on the front end of the motorcycle. This significantly improves chassis stability at highway speeds. The signature “flip” at the top edge is designed to kick the air up and over the rider, allowing it to settle as “clean,” non-turbulent air. This combination effectively eliminates the annoying helmet shake and wind noise often experienced with flat, vertical windshields.

Premium FMR Hard-Coated Polycarbonate

Durability is a core requirement for aftermarket Harley parts, and the Billboard Flare™ is built for the long haul. Each windshield is manufactured from Lexan® polycarbonate with a proprietary FMR hard coating. This material is significantly tougher than standard acrylic, providing excellent impact resistance against road debris and long-term chassis reliability. The hard coating also ensures the shield remains scratch-resistant and maintains its crystal-clear optical quality through years of Harley-Davidson maintenance and cleaning.

Direct Fit for Harley Detachable Hardware

The Billboard Flare™ is designed to be a direct replacement for the clear or tinted plastic on your factory Harley-Davidson Detachable Windshield brackets. It utilizes the existing hole patterns and hardware, making it a simple bolt-on instrumentation upgrade for your front end. Confirmed fitment includes:

• Sportster Models: XL883, XL1200, Iron, Forty-Eight, and Custom (1988–2022).
• Dyna Models: Street Bob, Low Rider, Super Glide, and Wide Glide (1991–2017).
• Note: Specifically designed to fit models using the 4-bolt “King” style detachable windshield mounting frames.

Improved Rider Endurance and V-Twin Performance

By creating a calmer “air envelope,” the Klock Werks Billboard Flare™ allows you to ride longer distances with less fatigue. It reduces the physical strain on your neck and shoulders, allowing you to focus on the V-Twin performance of your machine. This Stage 1 styling upgrade also enhances the visibility of your gauges and the clarity of any handlebar-mounted audio systems. Available in various tints, from a clear view for night riding to a Dark Smoke for a more aggressive, custom-bagger aesthetic, there is a Billboard Flare™ to suit every rider’s preference.

Installation and Care Tips

Installing the Billboard Flare™ is a straightforward task. Simply remove the hardware from your existing detachable frame, swap in the Klock Werks shield, and re-secure. To maintain the FMR hard coating, clean the shield using a soft microfiber cloth and a mild soap solution; avoid using ammonia-based glass cleaners which can damage the polycarbonate over time. During your regular Harley-Davidson service, ensure the mounting bolts are snug but not over-tightened to prevent stress on the shield’s mounting holes.
