One could say that the classic Indian fours were the Cadillacs of vintage motorcycles as they were smooth and flexible, equally at home trickling through traffic or cruising down the highway. At 77ci these Indians were some of the largest capacity motorcycles on the market. These features made them very popular with law enforcement agencies.
