Since I bought the Royal Enfield Himalayan in October I've added some essential accessories, including a USB charger, GPS mount and LED spots which are more for other drivers seeing me than anything else.
I also added rear racks for holding the saddle bags and yesterday, two brackets for the front guard for holding auxiliary fuel tanks, for which I'll carry one 5L tank on my up-coming trip to Puerto Madryn.
I've also changed over to an Iridium spark plug for better performance and changed the oil because I don't believe the dealer from whom I bought the bike, changed the oil and probably lied to me.
I've also put together a cable for attaching to the battery which I can use with the 12V air pump:
Hazard light switch also added.
