I bought a Suomy Spec 1R helmet as the first motorcycle helmet I ever bought.....so I knew nothing about helmets and what to look for etc.
I have had no experience with any other motorcycle helmet either so I can't comment with any authority...so in short...I have no idea what I'm talking about
however...that's never stopped Neka for saying anything

so I'll just tell you what the problems are with mine.
The side clip-on covers fell off...(probably cause I ride so fast

)..because they have this plastic thing that secures them on the helmet, which simply broke..(dunno why really).
The Visor is a pain to change...you have use a narrow ruler of something similar to get the side clip-ons off (but now they fell off so I don't have to anymore

).
Even after attempting several times to get the visor to fit snug it still allows air in around the visor (which is annoying in Winter cause its cold air).
The air coming past the visor gap causes a whistle as well..annoying.
The air ventilation system, located on the top of the helmet, works all year round and in winter, it blows freezing cold air on your forehead, which feels like ice blocks, and is really f#*%ed when everything else is warm except a freezing spot on your head.
You cannot open the front mouth vent with bike gloves on....also annoying and a bit dumb.
Otherwise it's a good helmet...haven't crash tested it though.

I live with fear everyday but on weekends she lets me ride.
