How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears.
At the back, the tape must run over the largest part of the back of the head (not too low on the neck). The tape may run slightly at an angle – what matters is that it sits all the way around the largest points of the head.
Make sure the tape measure sits snugly but does not dig in. Measure 2–3 times for the most accurate result. You can then compare the measured value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat (e.g. do not measure over a voluminous hairstyle)
- Keep the tape horizontal, i.e. 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 note on fit
The right helmet should fit firmly without causing uncomfortable pressure points.
A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

The Nexx X.R3R Zero Pro 2 in Carbon Gold Matt is the kind of helmet that earns its place on every ride — not just the track days. Built around a genuinely lightweight X-PRO carbon shell rated at approximately 1,350 g ± 50 g, it delivers real-world fatigue reduction whether you are commuting hard or chasing lap times, while the muted gold-on-carbon finish means it looks purposeful without demanding attention.
Key Features
- X-PRO carbon shell construction — extremely light at approx. 1,350 g ± 50 g, reducing neck fatigue on long rides and track sessions alike
- Race-optimised aerodynamic profile with integrated spoiler keeps the helmet planted at speed and minimises buffeting
- Air Dynamic System with 6 intakes and 4 exhausts, including Speed-Flow chin ventilation, for effective airflow even in slow traffic
- Wide-field Lexan-PC visor with scratch-resistant coating and magnetic X-LOCK closure for fast, one-handed operation
- ECE 22-06 certified with Double-D-Ring chin strap and emergency cheek-pad release for professional-grade safety
- Fully removable and washable antibacterial interior liner that dries quickly after hard use
- Three shell sizes across the XS–XXL range for a genuinely tailored fit
Everyday Usability Without Compromise
Where many carbon helmets demand you sacrifice comfort for weight savings, the X.R3R Zero Pro 2 is designed around extended wear. The ergonomic interior padding sits close without pressure points, the antibacterial, moisture-wicking liner stays fresh across multiple rides, and the wide visor aperture — both horizontal and vertical — gives you the situational awareness you need when filtering through traffic or threading a mountain pass. The Speed-Flow chin vent is particularly effective at low and medium speeds, where less-refined helmets tend to stagnate.
Performance at Pace
At higher speeds the aerodynamic shell geometry comes into its own. The spoiler and sculpted surface work together to bring the effective dynamic load close to zero at motorway and track speeds, meaning your neck muscles are not fighting the helmet at the end of a long straight. Vibration and turbulence are noticeably reduced, allowing you to maintain focus rather than manage discomfort. The X-LOCK magnetic visor system lets you crack or fully open the visor in a single movement without fumbling with gloves on.
Safety
The X.R3R Zero Pro 2 carries ECE 22-06 homologation, the current European safety standard required for road use across the EU and UK. The Double-D-Ring retention system is the benchmark fastening for motorcycle helmets, and the emergency cheek-pad release allows first responders to remove the helmet safely following an incident. These are not optional extras — they are standard on every size.
Design: Natural Carbon and Matte Gold
The Zero Pro 2 graphic exposes the woven carbon textile beneath a matte clear coat, overlaid with carefully placed gold accents. The result is understated rather than flashy — a helmet that communicates quality through material and finish rather than loud graphics. It pairs equally well with leathers on track and textile gear on the road.
