Joey was one of the greatest racers ever as well as being a bloody good bloke.
His family run the Joey Dunlop Foundation to help people with disabilities, you can find more information here: http://joeydunlopfoundation.homestead.com/milky.html
They’ve got some great merchandise at affordable prices too and all profits go to a very good cause.
Whenever it comes to helmets I’ve always preferred the simple designs, it makes them easy to spot at high speed and they always seem to be more memorable too. If you’re getting a custom job done it’ll probably work out a fair bit cheaper as well (if that’s a factor) plus it also leaves you with plenty of scope for developing the design over time while still keeping the original feel.
Like a lot of people one of my favourites is Senna’s, it’s simple yet still has personal significance because he’s used his national colours.
In the end though it’s got to be something you like, and I hope you’re going to post a few pictures once it’s done !
