I need to get her a cheapo lid so that she can ride with me on the back of my bike. Looking at spending as little as possible as she will not be a regular on the bike. I know, I know..."$10 helmet for a $10 head, blah blah blah" but I want to get her a decent lid for around $50 since she will probably only ride with me a few times. Anyhow, the lids that I am looking at are: Grex G06; M2R M1000, M10 or M5; MDS Edge; and Nolan Streetfighter Aero. These are all around $50-$60. Do any of these stand out as a "no-brainer" to get? Thanks for any and all advice!! Ride ON!!
