Why the OS20 RACE? The Offset Air Advantage

The defining feature of the OS20 RACE is its off-centred, left-positioned air inlet angled 20 degrees. This solves two problems that plague standard top-air helmets in tight cockpits:

• Added overhead clearance — the offset inlet clears roll cages, roof bars, and low cockpit rooflines that a centred inlet would foul
• Eliminates mic interference — the unique air channel placement prevents fresh air from "opening" the microphone and causing communication noise — a common problem with standard air systems
• Three individual air channels — route fresh air directly onto the visor to reduce fogging and keep contaminants out of the visual field

Frequently Asked Questions

Is the Impact OS20 RACE legal for MSNZ and Motorsport Australia events?

The OS20 RACE is Snell SA2025 certified. Snell SA2025 is accepted by both Motorsport New Zealand (MSNZ) and Motorsport Australia for applicable categories. Always verify the specific homologation standard required for your series with your series organiser or controlling body before purchasing.

What is the offset air intake and why does it matter?

The OS20 RACE features a left-positioned air inlet angled 20 degrees off-centre. This provides added overhead clearance in tight cockpits where a standard centred inlet would foul roll cage bars or roof structures. The offset placement also eliminates the fresh air system from interfering with the microphone — a common problem with standard top-air helmets.

What intercom system does the OS20 RACE come wired for?

The OS20 RACE is wired with a Rugged Radios helmet kit. Rex Harris can advise on integration with your specific intercom and radio system. Contact us →

Can I use the OS20 RACE with a Harris Race Radio system?

Yes. Rex Harris — ACMA/RSM certified radio engineer — configures the Rugged Radios wired kit for integration with Harris Race Radios systems. Contact us before purchase to confirm cable and connector compatibility with your specific radio.
