Which Stilo Helmet Do I Need?

Written by Aaron Harris — Barcelona 24 Hour class winner, Bathurst competitor and MotorSport NZ Licence Examiner. His licence-examiner role does not certify helmets or racewear. Rex Harris is a qualified radio engineer and NZ RSM/AU ACMA Approved Radio Certifier; that radio role is separate from helmet approval. Harris Race Radios has supplied motorsport helmets and communications equipment to NZ and AU competitors since 1975.

Use this quick guide to compare Stilo helmets by discipline. Check the homologation label and current event rules before choosing. For more detail see the Stilo Motorsport Helmet Guide — NZ & AU and the Helmet Knowledge Centre.

Confirm fitment and connector compatibility before ordering. Helmet homologation, not an employee's qualifications, determines which standards the helmet carries.

Common Questions

Can I use a Stilo helmet for both rally and circuit?
A compatible ST6 model may suit both; check the actual helmet's homologation and both series' rules. Venti WRC models are rally-oriented.
Do I need a carbon helmet?
Not necessarily. Carbon can reduce helmet weight; composite may be more affordable. Compare fit and homologation in our ST6 Composite vs Carbon guide.
What's the difference between ST5 and ST6?
The ST5 is no longer manufactured; ST6 is the current range. See our ST5 vs ST6 guide.
ST6 F or ST6 FN?
Choose based on the communications setup you actually use. See the Stilo communications guide or contact us with your connector and radio details.
Are the Stilo helmets from Harris Race Radios genuine?
Yes. We supply genuine Stilo products. Read our Stilo supply guide.
