But most riders begin with the 350cc models from Royal Enfield, such as the Classic or Meteor. They’ll sometimes trade their Cruiser 600s in when they get more experienced and can afford to upgrade to the Cruise 650. These are all factors that go into making this decision, increased power, of course, higher costs, different riding dynamics. Some say that 650 is a more refined experience and highway friendly performance, others say that 350cc bikes are more than enough for most riding purposes. Taking the debate beyond, it also ruminates on factors like maintenance costs, fuel efficiency and how exactly the upgrade to a bigger displacement bike makes sense in the Royal Enfield lineup.
