Alpha Technical features


the helmet must fit tightly 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.

SHELL SHELL in TRICARBOCO material, mix of Kevlar, carbon and fiber, joint through resine, hand made, using new technologies with vinilester resin.

The INTERNAL POLYSTYRENE produced in 3 sizes to get the best fitting. This characteristic allows a gradual and progressive absorption of the energy produced by the impact.
Even if the bigger part of the energy created by the impact is absorbed by the external shell, thanks to its deformation, the role of polystyrene is determinant for the absorption of the residual energy.
A diversified density of the polystyrene, permit us to optimize the mechanical performance of the shell/polystyrene.

D-RING retention system 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.


The internal polystyrene has been studied to work together wityh the air ventilations, put on the shell. The channels allow the perfect inside air flow and at the same time a quick outside air flow from back ventilation.


ALPHA is homologated as per the following rules:

ECE 22-05 Europe
DOT America and Canada
INMETRO NBR 7471 Brasil

You have to refer always to the homologation of the country in which the helmet is sold.
