Not a fan of those visor/sunglasses thingy things....i just go with the good old fashioned black visor...
..I've been mulling over what I wrote & now presume I'm a double-tool.. Had a copper discuss me riding quite fast with an open face helmet. Saying I should really use the drop down full-face feature if I wanted to keep all my teeth intact. Upto triple figures I rarely engage the chin-protector & I've still got all me front teeth guvnor!!
