Shafi I agree I have also stopped recommending because any body with high speed ride comes back with a sad face.. I have already mentioned the problem to Ali Vohra from whom I bought it and he understands, he proposed me LS2 Helmets I might try them.
Studds is nice brand and Shifter is there Top of the Shelf Product but we have to understand its a local commuting product for Indian roads with not very high speeds, it comes with very good quality build and finish and is approved by ISI Board but Its a no go for any one who have high Speed rides.
I am just keeping it for time being to move to some thing actually made for Cruiser/Speed bikes.
Imran bhai Studds Shifter is also ISI approved (some Indian safety Department i suppose) Iner is nice and soft, removable, anti scratch every thing... a Superb Copy.. but badly engineered...
as soon as you cross 100kmh or near to 100KMH you will constanly hear a loud noise like a Qinqi Rickshaw is tail gating you, and its been reported by many riders including @syedmoazzam but I did not payed attention to him until I ended up buying one ... lol
