A few people have been scammed on the site, Only use paypal to pay for items for sale by other members. If they will not use paypal, its likely a scam NEVER SEND E-TRANSFERS OF ANY KIND.
Installed mine yesterday morning and got to test it for about an hour. All I can say is perfect! I have it in the top position and there is minimal wind and wind noise. Now I can go back to my open face helmet.
After I installed the side bags I added the rear carrier. It ties it all together and makes a cleaner looking install and it' was only $139.00 at my dealer.
