Was contemplating for a long time in getting a new helmet since I got the Vulcan. It would be a modular mainly because I am wearing specs and it would get hot in the helmet while waiting in the traffic. The only helmet I have worn is the X-Dot 3/4 helmet.
For a long time I was leaning towards the LS2 which was within my (very limited and very little) budget. First I was thinking of getting the LS2 Metro Firefly, then the LS2 Valiant. Read and watched a lot of review about those 2 helmets until I came across the MT Helmets at the beginning of the year. I love the aggressive look especially their Atom SV line.
Asked a few owners from the MT Helmet facebook page and they said the helmet is nice and comfortable. They have no complains about the fit and it is quiet. The additional plus side is that it is within the budget. The only downside is that there aren't a lot of English speaking reviews on the net.
I also came across the Airoh brand and the only modular available in my little island is the Rides. Surprisingly it is also within the budget but as with the MT Helmets, there are little English version review of this helmet available in the net.
