The inner VPS (Vision Protection System) sunscreen is approved. In the box also in dark green (depending on the version), it really makes N21 a oneoff model.
A multitude of different classic and "vintage" looks are available thanks to a variety of colour combinations for the inner padding, shell edge and VPS edge, as well as the graphics and the shell itself.
The Microlock retention system, a ring to secure the helmet to the motorbike (Helmet Lock Ring) and the front aerators (availability depending on the version) complete the N21.
