WRS Kawasaki ZX-4R/RR (2023-2024) for +40MM Smoked High race Windscreen

1. Overview & Purpose

The WRS KA011F “Race High” Smoked Windscreen is a 40 mm (~1.6″) taller version of the stock screen, engineered to deflect high-speed airflow over your helmet for smoother riding at highway speeds or on the track, particularly for taller riders. Constructed from 2 mm DOT‑626 certified PMMA, it matches the Plexiglas used in MotoGP and WSBK screens—offering high clarity, lightweight flexibility, and durability. The smoked finish delivers an aggressive look while reducing daytime glare, complementing the ZX‑4R/RR’s sharp styling.

• Heritage Design: Developed using data from MotoGP/WSBK, the height and profile were refined for aerodynamic performance

3. Aerodynamics & Riding Experience

 Elevated Wind Protection

The 40 mm increase channels airflow above the helmet and torso, reducing chest-level buffeting and wind sweep. A Japanese Webike reviewer on the same screen noted less wind hitting the chest and more clean airflow in tuck ("wind…hits my face area," "wind can pass over the helmet even if I do not lie down all the way"). Riders over 6’1″ report a clearer air channel that reduces fatigue

 Comfort & Noise

Users report calmer helmet environments and less upper torso pressure, leading to reduced neck strain—common feedback for WRS high screens across bike models

 Glare Reduction

The smoked finish mitigates sun glare and headlight reflection during daytime riding, providing a subtle shield against bright light.

 Track Ready

With strategic height and smoke, the screen balances aerodynamic efficiency with rider visibility—ideal for track-use and aggressive road riding.

4. Installation & Fitment

1. Remove the OEM screen using T25/T30 Torx screws—retain the well-nuts.

2. Place the WRS screen using OEM mounting locations—no extras required.

3. Tighten bolts to 3 Nm—crucial for avoiding cracks in the acrylic

4. Check steering through full lock; slight adjustments solve any contact Include the supplied rubber throat-saver for glare and edge protection

5. Complete a short test ride and note sharper airflow and calm at speed.

The install is a 10–15 minute bolt-on job.
