Un-earthed this old helmet today as I was having a clean out.
Its a size 60 M3 Motostar made in 1992. Made in Newzealand.
Not sure if its worth anything because its old and retro but thought I would advertise it for $100 and see what happens.
Its virtually brand new, because I bought it and it didnt fit properly, was tight on the top of my head and gave me a headache after a while.
