I`ve got a Bell Moto 6 that I`ve had for years and I love it
It fits perfectly.
It`s comfy.
The venting works great.
The liner pulls out for washing and refits easily.
Scott goggles and a Scott half mask provide total face protection and are easy to get on or off.
The visor is very effective at keeping the sun out of your eyes as it goes lower than a lot of other brands.
I`ve worn it for a 4,500 mile ten day trip and had no complaints.
I`m not too sure about the cheaper plastic shelled Bell MX lids,but the top of the range ones look and feel great.
