Today I purchased a new helmet. Arai has worked really well and it saved my life in the resent accident, so I decided to stay in familiar brand and just got the newest version, Tour-X4.
Difference is not big between these two versions, mainly airflow has been improved in newest version.
I decided to have white colour again because it is coolest in sunshine and quite visible on a road.
Of course there would be cheaper options available, but I think helmet is a wrong place to save money…
