Price: ₹3,150.00


SMK Sirius is characterised by its external helicopter pilot-style visor, cream-coloured interior and refined metallic finishes. 

The external shell of SMK Sirius is moulded in EIRT (Energy Impact Resistant Thermoplastic), a thermoplastic resin, particularly resistant to impact, and has an aerodynamic shape that offers little wind resistance, ensuring silence inside the helmet. On its sides are metallic details that embellish and strengthen it.

The internal shell is moulded in differentiated density EPS, for better absorption of the energy resulting from an impact.

The visor mechanism is simple and functional, and allows for five different visor positions. The poly-carbonate visor includes a scratch-resistant system and is characterized by its particular helicopter pilot-style and by a laser-cut metal band that covers and strengthens the upper edge. It’s also Extra Wide Vision, meaning that the rider benefits from a much wider visual field than is standard. 

The practical internal sun shield is easily activated with a switch positioned on the left of the helmet, close to the visor movement mechanism. The inner linings, in an elegant cream colour, are breathable and hypoallergenic, fully removable and washable and ensure maximum comfort even after prolonged use.

The retention system is equipped with a practical quick release buckle for micro metric adjustment.

SMK Sirius conforms to ECE 22-05 homogenization.
