This is 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 around the widest part of your head – only then will you get an accurate result.
Place the measuring tape about 1-2 cm above your eyebrows at the front and run it along the sides above your ears.
At the back, the measuring tape should run over the largest area at the back of the head (not too low on the neck). The tape can run slightly diagonally – what matters is that it fits snugly around the largest circumference points of your head.
Make sure that the measuring tape is snug but not cutting into your skin. It’s best to measure 2-3 times to get the most accurate result. 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.
Fim homologated!
Experience the ultimate motorcycle helmet with the NHK GP-R Tech Race, which is FIM and an (AFRC) Advanced Fiberglass Reinforced Composite composite shell in five sizes that guarantees perfect fit and protection. The AFRC is a composite material that consists of a matrix and reinforcement fibers. The matrix is usually a polymer (e.g. epoxy resin), while the reinforcement fibers are made of glass fibers. With nine inner shell sizes and twelve helmet sizes, you will always find the ideal fit. Our 4D-air ventilation system ensures optimal ventilation and a comfortable fit, while the premium and comfortable inner lining offers maximum comfort. The helmet was aerodynamically tested in the MotoGP classes and has a flat visor with "Wide Angle View" for an extended field of vision. The PIN-Lock & Tear-Off-Ready Visor ensures clear view from all conditions. Thanks to the 100% full mechanical visor system, changing the visor is easy and quick. The removable and washable inner lining ensures easy care and hygiene. The helmet is also prepared for a "camel bag" and can easily be carried with glasses. The double D ring retention system and the cheek for acceptance offer additional security and stability. The helmet was tested in the wind tunnel to ensure the best performance at high speed.
