@KID MONK : You ride without permanent license??
MT Blade R series - Comes with D ring (as per Spartan site), so it can be worn on track days.
MT Optimus Quest - Doesnt come with D ring, so cant be worn on track.
MY Matrix - Comes with D ring
MT Axxis - Comes with D ring
And all the helmets can be worn for touring. And the speed thing"y" you are saying is known as wind noise. And it depends on person to person whether they are ok with it or not. And it can be curbed using earplugs.
P.S : If I know right every one has round shaped head. I have not seen any human being with square or rectangle head

P.P.S : Replying consecutively is against the forum rules, so edit the first post if you think you want to add anything.


second the blade series I saw on d j helmets ,Kochi didnt come with d ring system and they said they haven't had any d ring blade series helmets till now (on 26 November 2014) next what I ment by round was the shape of the helmet . The axxis series I have now is like an i20 after fluidic treatment 😊 its much much more aerodynamic than blade series
