I would spend the money on a Vanson or a Spidi. I have both. Looked at the Suzuki line of jackets from ICON and the reviews online weren't so hot. But I personally never wore on. There is a store in North Baltimore which has ICON stuff out the waazoo. But for $500-ish you could get a decent Spidi. I have a Vanson Hurricane for Summer. It's ventilated.
I really like Spidi stuff. It's quality gear.
