Technical specifications

Size guide

The table shows the full model range according to the manufacturer. For this color, we only have size XL in stock. Measure your head circumference with a tailor's tape measure just above the eyebrows, at the widest point; if in doubt between two sizes, choose the larger one.

Who is it perfect for?

It is the modular helmet for those who alternate city and travel: closed on the bypass and highway, open at traffic lights, gas stations, and stops, without taking it off and without breaking the law thanks to the P/J dual homologation. The internal sun visor and the Pinlock lens already in the box make it ready for all seasons from day one. The matte dark gray is understated and looks great on naked, touring, and maxiscooters. And unlike many discontinued items, spare parts can still be found here.

Frequently asked questions

What does P/J dual homologation mean?
It means the helmet is homologated in two configurations: P with the chin guard closed, like a full-face helmet, and J with the chin guard raised, like an open-face helmet. You can therefore ride legally even while open, which is not permitted on a helmet only homologated as P. ECE 22.05 homologation.

Why does it cost so little?
Because the first-generation Mathisse has been removed from the Airoh catalog, replaced in the range by the Mathisse II, and this is one of the last remaining stock pieces: it is a clearance price. The helmet is still new, boxed, and covered by the manufacturer's warranty, and spare parts are still available.

Is the Pinlock included?
Yes: the Pinlock lens is in the box and the visor is already pre-configured to mount it. It is the inner lens that removes fogging in the cold and humidity: it is applied once, before the first winter rides, and truly changes the use of the helmet.

Can I mount an intercom on it?
Yes, the helmet is Bluetooth-Ready, meaning it is pre-configured to house a communication system. The intercom is not included and must be purchased separately. On a modular helmet, it is advisable to choose a kit with a microphone that does not hinder the rotation of the chin guard.

Are spare parts still available?
Yes, and that is the strong point of this clearance item: Airoh still keeps spare parts for the first-generation Mathisse in its catalog, including clear, tinted, and mirrored visors, matte black, matte bronze, and glossy white chin guards, Stop Wind, liners, and air vents.

How much does it weigh?
The manufacturer declares a weight starting from 1,675 g, with a 50 g tolerance: this is the minimum value in the range, and the XL, which uses the second and larger of the two shells, is slightly heavier. Including packaging, shipping weight is approximately 2.13 kg.
