Hah. You're like me, intermediate oval doesn't fit.The K6 is a great helmet. It just did not fit me properly. Pressure point right in the middle of the forhead.
I like the visor meck better on the K6 than on my current RF1400 (only complaint that I have with the 1400)
If the K6 fits you properly, at that price, you cannot go wrong.
Thankfully AGV makes multiple shell sizes and it 'just fit'.
