I have 2 SENA Stryker helmets for sale. One black and one white. I bought them for my girlfriend and I but ended up getting rid of the bike - not to be replaced. I used the black one maybe a dozen times and the white one was only used twice. These helmets don't have a mark on them. These are equipped with their high-end Harmon Kardon speakers and microphones. On board FM radio reception AND you can stream audio from your phone or any other Bluetooth source. The sound quality is unsurpassed. The helmets come with everything that came with them when purchased. I also have a remote control (sold as an extra accessory) for the helmets that mounts on the handlebars. If interested, I have a Beeline MOTO GPS unit (https://beeline.co/pages/beeline-moto) that also mounts to the handlebars. And, a handlebar lock that immobilizes either the grip and clutch or the throttle and brake lever. When I bought the helmets, they had a suggested retail of $499 each - I really don't remember but I don't thing that I paid full retail. Now, however, they are on closeout for $299 each. I will let both go for $400. Call with any questions: six 6 nine - 2 four eight - zero 4 4 nine.
