How to Choose a Motorsport Helmet — NZ & AU Buyer's Guide
Why Harris Race Radios Carries the Largest Helmet Range in NZ & AU
Harris Race Radios holds the largest number of helmet models and the broadest range of helmet brands of any supplier in New Zealand and Australia. This is not an accident — it is a direct result of our core expertise.
A helmet is the most critical component in any motorsport communications system. Not all helmets are created equal, and not all helmets are compatible with all radio and intercom systems. The microphone type, speaker cup geometry, wiring harness connector, forced air inlet position, and shell construction all affect how a helmet integrates with your radio, intercom, and cooling system. Getting this wrong means poor communications, driver distraction, and compromised safety.
Harris Race Radios carries Roux, XRON, Stilo, Bell, Pyrotect, Impact, and more — across SA2025, SA2020, FIA 8859-2015, CIK-FIA, and Snell CMR/CMS standards — because our job is to match the right helmet to the right communications system for every driver, every series, and every budget. No other supplier in NZ or AU can do that across this breadth of brands and standards.

Step 1: Check Your Event's Helmet Requirements
Before you look at any helmet, check the regulations for your specific event and licence category. In New Zealand, refer to the MSNZ General Regulations and your event's Supplementary Regulations. In Australia, refer to Motorsport Australia Schedule D (Equipment).
Key things to confirm:
- Which standard is required — SA2025, SA2020, FIA 8859-2015, or any combination?
- What is the maximum permitted helmet age from date of manufacture?
- Are there category-specific requirements (e.g. karting requires CIK-FIA or Snell CMR/CMS, not SA-rated helmets)?
- Is this an FIA-sanctioned international event requiring an FIA standard?
Not sure? Contact Aaron Harris — MSNZ Licence Examiner — before purchasing. Getting this wrong is an expensive mistake.
Step 2: Understand the Standards Hierarchy
Motorsport helmet standards are not all equal. At the international level, FIA standards are superior to Snell SA standards — FIA events at international level require FIA-homologated helmets. For NZ and AU club through to national championship level, Snell SA standards are the dominant requirement.
FIA Standards — International Competition
| Standard | Use |
|---|---|
| FIA 8860-2018 ABP | Open-wheel international FIA competition (F1, F2, F3) |
| FIA 8860-2018 | International FIA closed-cockpit competition (WRC, WEC, GT) |
| FIA 8860-2024 | Current highest general FIA standard |
| FIA 8859-2015 | Accepted for NZ & AU championship and some international events |
Snell SA Standards — NZ & AU Club to Championship
| Standard | Status |
|---|---|
| SA2025 | Current latest standard — recommended for all new purchases |
| SA2020 | Previous standard — still accepted, valid until 31 Dec 2026 (MSNZ) |
| SA2015, SA2010, SA2005 | Accepted but ageing out — valid until 31 Dec 2026 (MSNZ) |
For a full breakdown of all accepted standards see our Motorsport Helmet Standards Guide.
For Karting
Karting requires CIK-FIA or Snell CMR/CMS certified helmets — entirely separate from SA-rated motorsport helmets and not interchangeable. See our Roux by Pininfarina Karting Helmet.
Step 3: Understand Helmet Lifespan
Helmet lifespan in motorsport is governed by two factors:
- Physical age: MSNZ recommends replacing helmets at least every 7 years. The foam liner degrades over time regardless of use.
- Standard expiry: Snell and FIA release new standards every 5 years and progressively drop the oldest standards from approved lists. In practice, a helmet becomes ineligible through standard expiry before physical age becomes the limiting factor.
The practical reality: helmets are effectively valid for up to 10 years — two standard cycles — before the standard they carry is dropped from approved lists. SA2005 and SA2010 helmets, for example, are currently valid until 31 December 2026 under MSNZ, after which they will no longer be accepted regardless of physical condition.
The smart approach: buy the latest standard (SA2025), replace within 10 years, and you will never be caught out by either physical degradation or standard expiry.
Step 4: Match Your Helmet to Your Communications System
This is where most drivers get it wrong — and where Harris Race Radios' expertise makes the difference. A helmet is not just a safety device; it is the primary interface between the driver and their communications system. The wrong helmet for your radio or intercom setup means:
- Poor microphone performance in high-noise environments
- Incompatible connector types requiring adapters or rewiring
- Forced air inlet positions that conflict with your cooling system hose routing
- Speaker cups that don't match your intercom's impedance or connector
| Your situation | What you need |
|---|---|
| No radio or intercom system at all | Base helmet (no comms fitout required) |
| One-way receive only (NitroBee, Quin Tracks, GT Members) | Helmet with 3.5mm speakers or speaker-ready cups |
| Two-way radio or intercom (driver to crew/co-driver) | Helmet with full comms — noise-cancelling mic and speaker pods |
| Already have a radio system | You still need a comms-fitted helmet — see Roux R1-F or XRON Integrated |
Harris Race Radios stocks adapter cables for all major radio and intercom brands. Contact Aaron Harris before purchasing to confirm the right helmet and cable combination for your specific setup.
Step 5: Do You Need HANS Posts?
If you run a HANS or FHR device, your helmet must have HANS anchor posts fitted. Most current motorsport helmets come with HANS posts as standard — always confirm before purchasing. MSNZ and Motorsport Australia require HANS/FHR devices for most categories. See our HANS & FHR device range and Helmet & HANS bundle deals.
Step 6: Choose Your Shell Material
| Shell Material | Weight | Best For | Price |
|---|---|---|---|
| Fiberglass | Medium | Club racing, endurance, Speedway, MEGA, rally | Most accessible |
| Composite | Light-medium | Off-road, karting, circuit racing | Mid-range |
| Carbon Fibre | Lightest | Serious circuit racing, endurance, premium off-road | Premium |
Step 7: Get the Right Size
Measure the circumference of your head at the widest point, approximately 2.5cm above your eyebrows. Match to the size chart for your chosen helmet model. If between sizes, size up. Contact Aaron Harris for personal fitting advice before ordering.

Frequently Asked Questions
- Why does Harris Race Radios carry so many helmet brands?
- Because a helmet is the most critical component in any motorsport communications system. Not all helmets are compatible with all radio and intercom systems. We carry the broadest range of brands in NZ and AU to ensure every driver gets the right helmet matched to their specific communications setup.
- Can I use my karting helmet for circuit racing?
- No. Karting helmets (CIK-FIA / Snell CMR/CMS) are not accepted for circuit racing, rally, or other motorsport events requiring SA or FIA-rated helmets. You need a separate SA-rated helmet for circuit racing.
- How long is a motorsport helmet valid for?
- MSNZ recommends replacing helmets every 7 years. In practice, helmets are accepted for up to 10 years — two Snell/FIA standard cycles — before the standard they carry is dropped from approved lists. Buy the latest standard and replace within 10 years and you will never be caught out.
- Is FIA better than Snell SA?
- At international competition level, yes — FIA standards are required for FIA-sanctioned international events. For NZ and AU club through to national championship level, Snell SA2025 is the current recommended standard and is accepted across all categories.
- Do I need a new helmet if I already have a radio system?
- If your current helmet doesn't have a noise-cancelling microphone and speaker pods fitted, you cannot use it for two-way radio communications. You need a comms-fitted helmet such as the Roux R1-F or XRON Integrated.
- Can I get expert advice before I buy?
- Yes — contact Aaron Harris (MSNZ Licence Examiner) for free advice on helmet selection, sizing, certification compliance, and communications integration before purchasing.
