let's start at the head...
helmet of course: best wind block there is
neckwarmer
moisture wicking long sleeve tee: many skiers/snowboarders wear them
another tee over that
sweatshirt
maybe another sweatshirt
agv reinforced leather riding jacket
any normal undies (i hear that some here prefer their wive's)
sweatpants or longjohns
sturdy demin jeans
retired snowboarding pants
3 or 4 layers of socks
hiking style riding boots
also, on the zx7r i installed the heated handgrip elements. they really help... just don't connect them to the hi beam power wire
unless you run your hi beams constantly
as you can probably see... i get cold. as long as you've got enough layers though... you can stay fairly cozy. and, believe it or not, i don't look like one of those babies with their arms sticking out cuz they have too many clothes on.
