Pyrotect Helmet Guide: Fit, Forced Air & Communications
A Pyrotect helmet needs to work as part of the driver's complete setup: the right helmet style and label for the racing, a secure fit, suitable air routing and correctly matched communications. This guide explains those decisions. For current models, sizes, prices and availability, browse the Pyrotect helmet collection. Use each model's product page for its exact specifications and communications choices.
Start with racing requirements, then fit
Check the current requirements for your discipline, class and event before choosing a helmet. Read the physical certification label on the exact helmet and check the permitted helmet style, condition and FHR requirements. SA2025 is the latest Snell motorsport standard; SA2020 remains relevant where current rules permit it. Neither label alone establishes eligibility for every event.
For speedway, check the relevant NZ or Australian class rules rather than applying general circuit or rally guidance. For any proposed junior use, confirm the exact grade, age group, governing body and event requirements. An adult small size or SA2025 label does not override a full-face requirement. Our motorsport helmet standards guide explains the checks to make.
Measure your head, but do not choose by measurement alone
Measure around the widest part of your head, above the eyebrows and ears, and use the size chart for the exact model. Head shape, crown contact and cheek support matter as well as circumference. A helmet should feel securely supported without painful pressure points or excessive movement. Do not automatically size up to make an uncomfortable helmet feel loose; a different shell shape or model may be the better answer.
Try the helmet with the balaclava, earpieces or other equipment you actually use. Check that speakers, microphone mounts and cables do not create pressure points, interfere with straps or compromise fit. Follow the manufacturer's fit checks and see our motorsport helmet fitting guide.
Compare forced-air layouts, not just model names
A forced-air helmet needs a compatible pumper, filter, hose and helmet connection. Inlet position affects hose routing, cockpit clearance and how easily the driver can move. Consider the seat, head restraint, roll cage, harness and driver changes rather than choosing a port position from appearance alone.
Compare the HC703 Pro Air Tri-Flow SA2025 12K carbon and HC705 Pro Air MFA SA2025 12K carbon by air routing, fit and selected equipment. Tri-Flow uses configurable standard, mid-forced-air or left-side-forced-air arrangements; confirm the supplied attachments and hose interface. MFA identifies mid forced air and is also found within the Pro Air Vortex naming family. Carbon construction does not itself establish the fitted communications.
The HB946 Pro Air Vortex MFA SA2025 composite helmet provides a separate composite-shell choice in flat black. It is not the HC705 carbon model. The older MIDAIR SA2020 composite wired package is a distinct stock-generation listing; check its physical label and available sizes. For side-air routing, compare the ProRace SFA SA2025 and its selected communications option.
Filtered air can help manage heat, dust and fogging, but performance depends on the whole system and the conditions. No inlet location guarantees a dust-free or fog-free helmet. Keep filters and hoses maintained, and check clearance and hose security before racing. Browse forced-air helmet equipment for related setup options.
Choose one of three communications configurations
The current ProRace SFA, HC703 Tri-Flow, HC705 carbon MFA, HB946 composite MFA and ProSport open-face listings offer three separately priced choices. Read the selected product variant, not the model name alone, to establish what is included.
- No Comms: the bare helmet without added speakers, microphone or communications lead.
- 3.5 mm Receive-Only: fitted helmet speakers with a receiver connection for compatible one-way race-control systems. There is no microphone or talk-back. Match mono/stereo wiring to the exact receiver; plug diameter alone does not establish compatibility.
- Full Two-Way Comms: microphone, speakers and communications lead matched to the intended radio or intercom, including off-road driver/co-driver systems. Check microphone requirements, connector and pinout before fitting.
Full communications adds NZ$179 to the bare helmet price. Open-face helmets also need a NZ$40 microphone boom, making the full open-face communications addition NZ$219. These amounts exclude GST. Use the current product selector for the complete configured price. Radios, receivers, vehicle intercoms, connecting vehicle equipment, air pumpers and hoses are separate unless explicitly included.
A full two-way kit may have a 3.5 mm earbud jack; that does not make it a receive-only kit. PCI and Rugged connections are not universally interchangeable. Check the actual helmet lead, microphone type, speaker or earpiece arrangement and connecting cable. Use the motorsport adapters collection to identify options, not as a promise that an adapter resolves every electrical mismatch.
Clear reception of NZ one-way race-control instructions or Australia's Race Management Channel, where required, helps drivers and teams respond to incidents. Confirm who must monitor the channel and how instructions reach the driver under the event rules. Two-way communications, where permitted, support pit instructions, endurance driver changes and early warnings about mechanical problems, helping protect equipment as well as improving operations. In off-road racing, a correctly matched intercom supports clear driver–co-driver coordination in a noisy cockpit.
Choose open-face helmets only for suitable uses
The SA2025 ProSport open-face helmet is available in gloss white, HW880 and gloss black, HB881. Colour is a buying choice, not a different application or certification. Compare fit, permitted helmet style, FHR hardware and the selected communications. Full two-way audio includes the required microphone boom. Follow the exact class rules rather than assuming an open-face helmet is permitted.
Check FHR hardware and replacement parts separately
Where an FHR device is required, confirm the helmet's provisions, compatible posts, device and installation instructions. M6 inserts alone do not establish compatibility with every HANS/FHR setup. Explore HANS and FHR devices for the appropriate equipment.
Replacement shields, tear-offs, liners and cheek pads must match the exact model, shell or shield where specified. Compare replacement shield finishes, the specific HS310420 blue anti-fog shield and the CruzArmor Pyrotect shield and tear-offs. Colour alone does not establish identical coating or fitment.
For interior parts, use the separate replacement cheek pads and corrugated headliner listings. Confirm the exact model, shell group and manufacturer part number. Pads refine an appropriate fit; they cannot correct an unsuitable shell. Do not assume composite-helmet pads fit carbon models.
For tear-offs, compare the Ultra Shield 20-pack and HA200020 200-pack. Check visor profile and post spacing, plus the event's tear-off rules.

Frequently asked questions
Should I choose a larger size if a Pyrotect helmet feels tight?
Not automatically. Check the exact model's chart, head shape, crown contact and cheek support. Painful pressure points may require another model rather than a loose-fitting larger helmet. Check fit with your normal balaclava and audio equipment.
What is the difference between forced-air position and communications?
The air inlet concerns the air supply and hose routing. Communications concern the microphone, speakers or earpieces, wiring and radio or intercom connection. Select and check them separately.
Are all Pyrotect helmets supplied unwired?
No. The current model listings offer No Comms, 3.5 mm Receive-Only and Full Two-Way Comms. Read the selected variant and confirm its actual microphone, wiring and connector requirements.
Does a 3.5 mm earbud jack mean a kit is receive-only?
No. A full two-way microphone-and-speaker kit can also have an earbud jack. Receive-only means listening without microphone or talk-back.
Does a new SA2025 supplier listing change my SA2020 helmet's rating?
No. Check the physical certification label on your exact helmet, its condition and current class and event requirements.
Does wired offroad mean it works with every intercom?
No. Check the supplied helmet kit, connector, microphone, speaker or earpiece arrangement and cable against the particular intercom or radio.
Can an open-face helmet be used in junior speedway?
Confirm the current rules for the exact grade, age group, governing body and event before purchase. An adult small size or SA2025 label does not override a full-face requirement.
Where should I compare models and current prices?
Use the Pyrotect collection for the range and each product page for sizes, configured price, specifications and package contents. This guide explains fitting, air routing and communications decisions.
