Recently got my hands on the new BS 4 compliant Royal Enfield classic 350 silver , its not only the environment friendly upgrade but also more of a refinement in the engine for a smoother ride and a better fuel efficiency.
The first thing you notice is that there is no switch for headlight as you turn on the bike the headlight turns on which has been done as per the safety guidelines of indian government. And if you look more closely the carburetor has two pipes now , which link to a device sitting behind the engine.
This device works on the emitted pollutant gases and makes the bike more environment friendly.The bike is a bit more smoother , little less vibrations than before.So friends Enfield is now BS 4 compliant and you can enjoy the royal ride being environment friendly.
