any helmet from Arai is overpriced
even €80,- helmets pass standard safetylaws and after €400,- it's just luxury and paintjob you're paying for
anything past €600,- is just crazy
the Yamato helmet may be limited, but there are no safety tests needed nor does it have any luxury
Only cost has been the design and the liscense
So unless it has a Kevlar shell, anti fog/scratch visor, onboard Dolbi Pro-logic I see no reason for it to cost past €1000,-
