I wear mine in all models I fly.
I even wore it on the bike once.....but it looked a bit silly.
I have 2 SPH5 helmets for sale for $1000 canadian each. Only 2 years old and used about 300hrs total (...if that) I have personally had two friends die that would've survived the crash if they had the helmets on. How much is your life worth?
You pay shipping.
PM me if you are interested.
