The Bell HP77 is the top-tier FIA 8860-2018 homologated racing helmet in Bell's current range, worn by Zhou Guanyu across every round of the 2024 FIA Formula 1 World Championship. Carrying race number 24 for Stake F1 Team Kick Sauber — officially entered by Sauber Motorsport AG — Zhou completed his third consecutive F1 season as the sport's only full-time Chinese driver. Spark Model's 1:5 scale model of this helmet translates that season into a tangible, display-ready collector piece.
The Bell HP77: F1's FIA 8860-2018 Standard
Bell's HP77 sits at the top of the company's competition hierarchy, built to the demanding FIA 8860-2018 Advanced Helmet Standard — the most stringent homologation in circuit racing. Its distinctive visor geometry, pronounced chin profile and tightly integrated aerodynamic shell distinguish it clearly from lower-specification lids. Zhou Guanyu ran Bell-supplied HP77 helmets throughout the 2024 season, making it the definitive reference for his 2024 personal livery.
Car No. 24, Sauber C44 — A Season in Transition
Zhou Guanyu's 2024 helmet design blends Stake F1 Team Kick Sauber's green and black team palette with personal motifs referencing his Chinese heritage, carried on the Bell HP77 across all 24 rounds of the championship. His partner at the team was Valtteri Bottas, and the constructor ran the Sauber C44 chassis throughout the year. Stake.com and Kick, the streaming platform, held primary title-sponsorship rights — a branding that will be replaced entirely when the team transitions to Audi factory status. Zhou has held race number 24 since his 2022 debut, giving collectors a clean numerical thread across three Spark helmet releases.
Spark Model's 1:5 Scale Resin Helmet
Spark Model produces a dedicated line of 1:5 scale replica helmets covering the current Formula 1 grid. Each piece is a hand-painted resin model, and the 1:5 ratio gives Spark's painters the surface area to faithfully reproduce intricate personal liveries — the blue, green and white colour elements of Zhou's 2024 design among them. SKU 5HF148 is the catalogue reference for this specific season helmet. The larger format also allows the HP77's characteristic visor shape and chin profile to read accurately in miniature form.
In the Display Cabinet
This piece pairs naturally with Spark's 1:5 Valtteri Bottas Stake F1 Team Kick Sauber 2024 helmet to complete the teammate set from the Sauber C44 year. Alongside Zhou Guanyu's earlier Alfa Romeo-era Spark helmet releases from 2022 and 2023, it also documents his full three-season F1 career to date in a coherent series. Collectors building a Bell brand set or a broader 1:5 F1 helmet grid will find it an obvious anchor piece for the 2024 Sauber chapter.
