'Bikes are my passion and I take care of my helmets as my babies. Like people go and buy clothes, I go shopping for helmets. I have different helmets for different days,' John told reporters here, Wednesday.
'People feel I'm crazy, but I love shopping for my helmets and I have all major brands,' he added.
The 36-year-old actor who is the brand ambassador of Yamaha, was in the Capital to launch three new bikes - Vmax along with limited edition of Fazer and FZ series.
After launching the motorcycles, John talked about safety measure that bikers should keep in mind while riding.
'Safety is very important and that's why helmets should be a biker's priority. Safety of pillion riders is also important and they should also wear helmets,' he said.
'Indian roads, mainly Mumbai is not very conducive for two wheelers. There are riders who don't take any precautions and are very irresponsible. On the other hand, there are people who walk on the road without thinking and taking care,' said the actor who will be next seen in films like 'Hook Ya Crook' and '1-1800 Love'.
