How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible measuring tape.
It is important that the measuring tape runs at the widest part of the head – only then will you get an accurate result.
Place the measuring tape about 1–2 cm above the eyebrows at the front and run it along the sides above the ears.
At the back, the measuring tape should run over the largest point of the back of the head (not too low in the neck). The tape can run slightly diagonally – what matters is that it sits around the largest circumference points of the head.
Make sure that the measuring tape is snug but not cutting in. It is best to measure 2–3 times to get the most accurate result possible. You can then compare the measured value in centimeters (cm) with our size chart.
Tips for an accurate result
- Lay hair flat (e.g., do not measure with a voluminous hairstyle)
- Run the measuring tape horizontally or along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model/fit)
Important for fit
The right helmet should fit snugly without causing uncomfortable pressure points.
A new helmet may feel a bit tighter at first, as the inner padding will adjust slightly over time.
Racing DNA for the street – and for those who don't compromise on their helmet. There are helmets that look fast. And there are helmets that come from a development process that truly originates from motorsport. The Alpinestars Supertech R10 Helmet Arius Double Red Gloss clearly belongs to the second category.
From the first moment you put it on, you feel: This is not a "normal" sport helmet. The R10 is designed for protection, aerodynamics, stability, and lightweight construction – developed over many years and tested under racing conditions. The result is a high-performance carbon racing helmet that impresses on the road just as much as during ambitious outings on the racetrack (depending on regulations).
The Arius Double Red Gloss graphic provides exactly the look that a top-level helmet needs: aggressive, noble, unmistakable.
Why the Supertech R10 is so special
The Alpinestars Supertech R10 was developed for riders who want to get the maximum out of their helmet – in terms of safety, airflow, and riding stability at speed.
Your advantages at a glance:
- Carbon multi-composite shell for high strength at low weight
- ECE 22.06 / DOT / FIM homologated (street & racing-oriented use)
- Optimized aerodynamics through CFD and wind tunnel development
- Dual spoiler system (race and road spoilers included)
- 11-fold ventilation system for Cooling, breathability, and fog reduction
- Optical Class-1 visor (3 mm) with anti-scratch coating
- Tool-free visor change with metal locking
- Extensive delivery scope with 2 visors, Pinlock, tear-offs, and more
Protection at the highest level – for maximum control at the critical moment
With the Supertech R10 Carbon helmet, protection is at the forefront. The multi-layer carbon composite shell is designed for controlled energy dissipation and efficient force distribution. This concept is complemented by a multi-density EPS inner shell with several density zones as well as a low-friction EPS inner surface.
Additional details such as the emergency cheek pad release system, optimized chin area, and the well-thought-out interior demonstrate: Here, not only weight or optics were considered, but the complete protection system.
Note: The mentioned performance values (including internal impact tests) are based on manufacturer specifications / internal tests by Alpinestars.
Aerodynamics & Stability: Developed for high speed
A fast helmet must not only be lightweight – it must also be stable in the airflow. The Alpinestars R10 racing helmet has been developed using CFD and in a wind tunnel to optimize drag, lift, and aeroacoustic properties.
Especially strong:
- Race and road spoilers for different setups
- Side winglets and visor turbulators for increased stability and efficiency
- Patented elastic release system of the spoilers to support impact management
The result is a helmet that remains stable at high speeds – giving you more confidence in your line, braking point, and focus.
Ventilation & Comfort: Fresh in the head, clear in the view
Especially during sporty riding, a good climate inside the helmet determines concentration. The 11-fold ventilation system of the R10 directs air precisely through the helmet, thus supporting Cooling and breathability. At the same time, the system helps actively reduce visor fogging.
Important for everyday use as well as for the track:
- Pinlock® 120XLT-compatible visor
- Breath deflector and wind deflector included
- A-Head fitment system for adjusting helmet height and angle
- Cheek pads available in various thicknesses (for fine-tuning the fit)
Visor System: Racing-ready from the factory
The visor system is designed for performance and everyday usability. The 3 mm thick optical class-1 visor provides a clear view and is equipped with an anti-scratch coating. Thanks to the metal locking mechanism, the visor sits securely, and the tool-free quick change saves time.
Perfect for track & street:
- 2 visors included: clear + dark tinted
- Tear-off pins already prepared
- Tear-off set included
- Pinlock® lens included
Delivery scope (strong for price-performance in the high-end segment)
