The SRL2 is compatible with the Shoei Neotec II if it was manufactured on or after March 8th, 2019 and the Shoei GT-Air II.
Here is how to determine if the Shoei Neotec II was manufactured on or after March 8th, 2019:
- The 5 year warranty sticker on the outside of the package is blue.
- The sticker on the visor has the following text below the INTERCOM READY DESIGN "Designed for seamless integration with SENA SRL/SRL2 Communication Systems".
- There is a white sticker underneath the center liner that shows the production date "Product Month/Day/Year" along with the serial number of the helmet.
- The shape of the cutout that is located on the right side of the helmet underneath the cheek pad is long enough to support microphone for the SRL2.
