Helmet: Get the best quality full-face helmet
you can afford and ensure it fits snuggly around your
entire head. Remember that the protective padding
in a new helmet will 'pack' (i.e. compress) where
there is pressure, so go for a very snug fit initially
and eventually it should mold to fit your head.
Some head shapes fit better in Arai, others in Shoei,
so choose the helmet for the fit and the quality,
not for the brand or the graphics.
Ensure the helmet has an ACU approved gold stamp,
and the visor has a British Standard logo engraved
