Originally had a Shoei Raid II - nice but used to get horrendous wind-buffetting when doing a right-shoulder check at 60+mph down M-way, so decided to go for the XR-1000 (after a fall) because I'd read somewhere that the hydrofoil strip across the back of the lid helps to stabilise the riders head at high speeds. Didn't think it would make such a BIG difference but it DOES!
Can't believe nobody has mentioned this "advantage" before either
