That's like everything else what you want & who's doing it, I have somewhere around 15 helmets from dirt bike to boat racing over the last 40 years of punishing my body (& wallet) one of my desert truck racing helmets cost a grand & took him 2 months of air brushing, that black one pictured has gold leaf in the lettering & Sylvester the cat rubbing his hands together was my painters idea cause I'm always scheming up crazy ideas while riding that one took all of a day & cost $400 (gold leaf)
It's whatever you want to spend if you do the troy Lee thing it starts around a grand & goes up from there plus a year wait if he's never done one before.
Everytime I walk into cycle gear some tight azz is bickering about helmet costs & me being me blurts out while walking past "if you have a $100 head buy a $100 helmet" witch usually gets me the evil eye from the customer I don't even know.
Or care to
