Arai VZ-RAM NAKASUGA4: Honoring a Legend’s Final Season
Japanese motorcycle racing legend Katsuyuki Nakasuga has announced his retirement from the JSB1000 championship at the end of the current season. To commemorate his historic career, which includes 13 championship titles, Arai has released the VZ-RAM NAKASUGA4 helmet. The open-face model, priced at 74,800 JPY, features Nakasuga’s signature “lucky cat” eyes, tiger graphics, and his iconic number 21.
Why is the NAKASUGA4 series significant for collectors?
The NAKASUGA4 design serves as a visual timeline of the rider’s dominance in the All Japan Road Race Championship. According to Supermoto8, the design first debuted on the full-face RX-7X model in January 2023. By moving this livery to the VZ-RAM, Arai provides a rare opportunity for street riders to wear a professional racer’s signature look. The inclusion of the “lucky cat” motif and the number 21—a symbol of the Yamaha factory rider’s tenure—anchors the helmet as a high-value collector’s item for fans of the JSB1000 series.
Katsuyuki Nakasuga has achieved a record-breaking 13 championship wins in the JSB1000 class and has secured four victories at the prestigious Suzuka 8 Hours endurance race.
How does the VZ-RAM compare to full-face performance?
The VZ-RAM is often described by enthusiasts as a “full-face helmet without the chin bar,” offering a bridge between daily utility and track-ready protection. Per Arai’s technical specifications, the helmet utilizes the PB-cLc2 construction derived from Formula 1 safety research. This design prioritizes a smooth, rounded shell intended to improve “glancing off” performance during an impact. While traditional full-face helmets like the RX-7X offer more total coverage, the VZ-RAM shares the same Type12 diffuser and IC-5 intake systems, ensuring that cooling efficiency remains consistent with top-tier racing gear.
What safety certifications does the new model carry?
Safety remains the primary focus for Arai, and the VZ-RAM NAKASUGA4 is no exception. The helmet meets both SNELL and JIS (Japanese Industrial Standards) certifications, as confirmed by the manufacturer. The interior features an antibacterial, odor-resistant liner, while the VAS-Z shield system is designed to maintain a low center of gravity. This balance is particularly important for riders performing long-distance touring, where weight distribution can significantly impact neck fatigue over time.
Pro Tips for VZ-RAM Owners
- Shield Compatibility: The VAS-Z system allows for the optional Pro-Shade, which acts as a sun visor for varying light conditions.
- Fitment: With sizes ranging from 54cm to 62cm, ensure you measure your head circumference accurately, as Arai’s internal shape is distinct from other major brands.
- Maintenance: Keep the Type12 diffuser vents clear of debris to maintain the airflow performance Arai designed for high-speed stability.
