My helmet was designed by BHDesigns and painted by Steve at SJD, couldn’t recommend Steve more, very professional and always kept me in the loop with design changes.
the design is a fluro yellow and Fluro red, bordered by black pin stripes and the main piece is the chrome ‘M’ on each side.
You'll find alot if not most do indeed get their lid either painted or wrapped. Various specialized firms can help you with deisgns and carry out the work etc.
