Modern helmets are cheaper to produce, cooler, and lighter. They stand less chance of protecting against non-rotational forces, but that doesn't hurt sales because 99.99% of people buying helmets are too lazy to check what the spec is on the helmet they buy.

The biggest advantage of the lexan shell is not pentration resistance but that will will maintain integrity when it hits a rough road surface at 20mph: if it doesn't, then the liner won't absorb energy.
