Dangerous on sport bikes
I really loved the helmet. Comfort, the best air flow I've found on any of the 10 helmets I've had, so quiet the airflow can be heard "around" the helmet on a low whistle. Perfect fit and nice shaded visor.

BUT ON MY R1, VISIBILITY IS DANGEROUSLY IMPAIRED. Ok, if you don't mind having to tilt your head up constantly to see over 20 feet in front of you, then buy all means, get it. For any ride over 15 mins, this is very tiresome. It is not possible to relax your neck and have good visibility forward. I even tried various sizes thinking it had to be me. Went to 3 stores (did I mentioned I loved the helmet?), but they admitted visibility was restricted. An "aggressive" riding posture is required. A shame, I really wanted t like this helmet.

Love it.
Exactly what I expected. Very comfortable, cool, and light. The visibility is superior to any other helmet I have owned. Had a minor problem with the internal flip-down visor (damaged during manufacture), but Revzilla replaced it very quickly and without difficulty.

After fifteen years it was time for a new "lid". I have been very happy with my previous helmet, also an AGV, and I'm looking forward to using this K5, with its improvements.
