Bell Moto-10 Spherical Strike MIPS Adult Off-Road Helmets
As leaders in head protection, one thing has stayed the same since we developed the first full-face motocross helmet in 1975 — we never stop breaking our own boundaries. Thriving on the progression of helmet development, we're determined not to follow trends, but create leading solutions that keep riders performing at their best. Meet the Moto-10 Spherical — the evolution of the Bell Moto series. Born from the needs of top athletes around the world like Eli Tomac, the Moto-10 is our most advanced off-road helmet that sets a new industry standard. As a direct result of our athletes' influence and feedback, the Moto-10 achieves a winning combination of increased protection, weight reduction, and extreme airflow, enhancing the rider's experience and confidence. As racing evolves, so do we. Combine our new technologies with our favored Bell fit and aggressive styling, and the Moto-10 not only emerges as the front-runner — it becomes the evolution of full-face protection.
- SPHERICAL TECHNOLOGY™ — Spherical Technology™, powered by Mips®, helps redirect impact forces, bringing market-leading design, performance and brain protection together without compromising comfort, ventilation, weight, or style.
 - SEGMENTED 3K SHELL — Special shell design that provides a large exhaust vent that expells hot air out of the helmet, ensuring the rider stays comfortable and cool.
 - THERMAL EXCHANGE AIRFLOW SYSTEM™ (T.E.A.S.) — Our most extreme ventilation system that sucks in cool air like a vacuum and then expels hot air through the side and rear exhaust ports.
 - NO MISSED RACES (NMR™) BUMPERS — Using a softer EPP material, two bumpers on either side of the helmet compress under load but bounce back to its original form, reducing the likelihood of further injury caused from the helmet contacting your body.
 - PANORAMIC GOGGLE PORT — A wider port provides better fitment, optimal sealing, and a massive field of view, increasing the rider's visibility and safety when needed most.
 - MAGNEFUSION™ CHEEK PAD EMERGENCY RELEASE SYSTEM — Allows for easy removal of the pads for washing and enables emergency responders to easily remove the cheek pads first before removing the helmet following an impact.
 - SWEAT MANAGEMENT — With the combination of the T.E.A. System, Spherical venting channels, and Segmented shell, we created the ability to force perspiration across the rider's brow — away from their goggles — preserving vision late in a race
 - COOLJADE™ COMFORT LINER — This removable, washable liner is made of recycled jade fabric to create a natural cooling effect. The ultra-wicking construction combined with CoolJade-infused yarn decreases your skin surface temperature up to 10? F — keeping you cool, comfortable, and focused on the race at hand.
 - FLYING BRIDGE™ VISOR — This visor design allows more flexibility and improves airflow across the helmet.By not using a traditional center post and screw concept, we're able to increase the amount of energy management material in a high-impact zone.
 - THERMAL EXCHANGE AIRFLOW SYSTEM™ (T.E.A.S.) — Our most extreme ventilation system that sucks in cool air like a vacuum and then expels hot air through the side and rear exhaust ports.

HELMET SIZING
Measuring the head is only a starting point for the entire sizing procedure. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet. A small metal tape measure or a cloth tape may be used to make your initial measurement. You can also use a string, which can then be laid against a measuring tape.
(H) Head
Measure the circumference of the head at a point approximately one inch above the eyebrows in front, and at a point in the back of the head that results in the largest possible measurement. Take several measurements. The largest measurement is the one you want to use.
