Honestly, these helmets are just below average. in India, Studds,Steelbird-Bieffe,Vega,AGV,MPA are the top brands. these are ISI(Bureau of Indian standards) approved as all Indian made helmets are made(Lot of duplicate,substandard helmets are made btw indistinguishable too), but that does not mean it is world class. but, many imported ones are available with proper safety standard certifications PASS(I think DOT) like daijya. a good helmet costs 70$(around 4500-5000 Indian rupees). those buying a $2000 Motorcycle can sure afford a $100 helmet for the safety.
