Alpinestars Supertech R10 Helmet Arius Double Red Glossy – 8203926-1683

All-day wearability meets uncompromising race-spec engineering in the Alpinestars Supertech R10 Arius Double Red Glossy. Shaped for riders who demand a secure, dialled-in fit whether they are commuting fast or attacking a track day, the R10 wraps its carbon-multi-composite shell around an interior precision-engineered to move with you, not against you — from the first kilometre to the last.

Key Features

• Carbon-multi-composite shell (3K carbon, UD carbon, aramid, fibreglass) delivers exceptional rigidity with a weight of approximately 1,540 g in size M
• ECE 22.06, DOT and FIM homologated for road and racing-oriented use across multiple regions and regulations
• A-Head Fitment System allows fine adjustment of helmet height and angle for a truly personalised, fatigue-free fit
• 11-stage ventilation system actively channels air through the helmet to keep you cool and reduce visor fogging on long rides and track sessions alike
• 3 mm optical class 1 visor with anti-scratch coating and tool-free metal-locking quick-change mechanism
• Dual spoiler system — race and road spoilers both included — developed via CFD analysis and wind-tunnel testing for high-speed stability
• Generous box contents: clear visor, dark-tinted visor, tear-off set, Pinlock 120XLT insert, two spoilers, chin deflector, breath deflector and helmet bag

Built for the Long Haul — Comfort and Fit in Detail

What separates the Supertech R10 from a purely track-focused race helmet is how thoughtfully its comfort systems have been developed for extended wear. The A-Head Fitment System lets you adjust the helmet's height and angle so the shell sits precisely where your head geometry demands, eliminating the pressure points that accumulate over a long ride. Cheek pads are available in multiple thicknesses, giving you the granular control to fine-tune lateral contact without sacrificing the snug, confidence-inspiring fit that matters when speeds rise.

The multi-density EPS liner features several distinct density zones, each tuned to manage impact energy efficiently while the low-friction inner EPS surface helps the helmet settle naturally onto your head. An emergency cheek pad release system is integrated for first-responder access, a detail that speaks to how seriously Alpinestars treats the complete protection package.

Protection Architecture

The multi-layered carbon composite shell is engineered for controlled energy dissipation and efficient load distribution across its surface. It combines 3K carbon, UD carbon, aramid and fibreglass in a construction refined through years of MotoGP and World Superbike development. The result is a shell that absorbs and redirects impact forces rather than transferring them directly, working in concert with the multi-density EPS liner to deliver protection at the level that FIM homologation demands.

Note: Performance figures relating to internal impact test data are based on manufacturer specifications and internal Alpinestars testing.

Aerodynamics and High-Speed Stability

Stability at speed is inseparable from confidence, and the R10's aerodynamic package was developed to keep lift, drag and aero-acoustic noise in check. CFD simulation and physical wind-tunnel sessions informed every surface, from the pronounced lateral winglets and visor turbulators to the interchangeable spoiler system. A patented elastic spoiler release mechanism supports impact management without compromising the aerodynamic platform during normal riding.

• Interchangeable race and road spoilers for different setups — both included in the box
• Lateral winglets and visor turbulators optimise stability and aerodynamic efficiency
• Patented elastic spoiler release system aids impact energy management

Ventilation — Clear Vision, Cool Head

The 11-stage ventilation system is one of the R10's most rider-focused attributes. Intake vents draw air across the crown and brow, feeding channels that run through the EPS liner and exit through rear exhausts, creating a through-flow that keeps internal temperature down during spirited riding. The same airflow management actively helps reduce visor fogging — a particular benefit on cooler mornings or when transitioning between speeds on a track day.

• Pinlock 120XLT-compatible visor included for maximum anti-fog performance
• Chin and breath deflectors supplied to manage airflow around the face
• Adjustable vents allow you to tune airflow to conditions

Visor System — Ready for Road and Track

The 3 mm optical class 1 visor offers distortion-free vision across its full width. The anti-scratch coating protects clarity over time, while the metal locking mechanism ensures the visor stays sealed against wind noise at motorway speeds. Tool-free quick-change means swapping between the included clear and dark-tinted visors takes seconds — ideal at a track day when light changes between morning practice and afternoon sessions.

• Clear and dark-tinted visors both supplied as standard
• Tear-off pins pre-fitted; tear-off set included
• Pinlock 120XLT insert included

Arius Double Red Glossy — The Graphic

The Arius Double Red Glossy graphic brings a layered, aggressive character to a helmet that already commands attention through its aerodynamic silhouette. Deep gloss red tones shift subtly with light, giving the R10 a premium, race-paddock presence that reads as clearly on the road as it does in pit lane.

Size Guide

Measure your head circumference at its widest point — across the eyebrows and above the ears — using a flexible tape measure, then match to the chart below:

• XS: 53–54 cm
• S: 55–56 cm
• M: 57–58 cm
• L: 59–60 cm
• XL: 61–62 cm
• XXL: 63–64 cm

Fit tip: cheek pads are available in multiple thicknesses to let you personalise the lateral fit without changing shell size.

Fitment and Compatibility

The Alpinestars Supertech R10 is a universal full-face helmet designed for road and racing-oriented use. It carries ECE 22.06 homologation for use on public roads across Europe, DOT homologation for North American markets, and FIM homologation for competition use subject to the relevant series regulations. It is not officially listed as compatible with a specific Bluetooth or intercom system; compatibility with aftermarket communication devices depends on the individual system chosen.
