Shell made of TRI-fiber composite that allows to get a lighter shell but, at the same time, a more protective. 
The outer shell, made of tricarboco fiber, a mix of kevlar, carbon and fiberglass with different weights/breaking loads linked up; loads, linked up with aramid resins ensures a lighter, harder more safety and impact resistant shell
To satisfy even the most demanding and professional riders, MX SPEED is made in 2 different shells: M and L.
The internal polystyrene is made of 2 different sizes to obtain the best ergonomics with different thickness. This characteristic allows a gradual and progressive absorption of the impact force generated by an impact. Although most of the energy due to an impact is absorbed by the outer protective shell due to its deformation, the role of polystyrene is decisive for the absorption of residual energy. A different density of the same polystyrene allows to optimize the mechanical performance of the shell-polystyrene complex, ensuring the maximum degree of absorption in all areas of the helmet itself.

Inner liner and cheek pads are removable, washable and replaceable.
They are in precious bielastic fabric with specific fibers that offer the following characteristics:
• Rapid flow of moisture from the water
• Maintaining optimal temperature
• Light, soft and breathable fabric

The air intakes are designed to increase internal comfort, the air flow is channeled into the inner shell through 4 large front openings protected by solid metal meshes.
The internal polystyrene protection and comfort liners have been optimized to work in symbiosis with the large air intakes. 
The particular grooves, made on polystyrene, allow the incoming air flow to have optimal ventilation inside the helmet and, at the same time, a quick exhaust of the hot air flows coming out from the rear air intakes.

MX SPEED is equipped with MIPS, developed in Sweden that reduces rotational motion by absorbing and redirecting rotational energies and forces transferred to the brain from angled impacts to the head.

To have a maximum safety the helmet must fit tightly and be correctly and securely fastened, in order not to be able to be taken off neither by pulling it nor by rotating it around the head.

If it is too big, it may slide down over the eyes or turn in a lateral direction due to movement during riding, blocking the right visibility. 

OUTER SHELL in tricarboco material, mix of Kevlar, carbon and fibre, joint through resin hand made using new technologies, which foresee aramidic resins.
INTERNAL POLYSTYRENE protective lining, available in three sizes (S, M and L). The special shape and construction in different density increases mechanical resistance in the event of accidental shock. Inner channels studied in the wind tunnel guarantee a perfect ventilation. 

The D-RING RETENTION SYSTEM has been designed and patented by Suomy. 
Insert the free side of the strap in the rings. Pull the end until the strap presses firmly against the jaw. 
After this operation, it should not be possible to remove the helmet. Verify that by grabbing it from the back and rotating it to the front it cannot be removed and it is fixed to the head. If the helmet tends to come off or rotates freely, tighten the strap again until the right pressure is obtained and repeat test.
If after repeating the test you are not able to efficiently tighten the retention system, do not use the helmet. Only after checking the correct tension of the strap, fix the free end locking it with the automatic stud to the release tab.
The automatic stud is necessary only to fix the free end of the strap to prevent it from flapping while riding. Fixing the release button does not assure that the helmet is correctly in position and properly fastened: the correct locking of the strap must be verified exclusively following the above paragraphs.
To release the retention system, release the automatic stud button and pull the release tab to loosen the closure. Slide out the free end of the strap from the «D Rings». Use the release tab only to remove the helmet! Never release this tab while riding.
