One of the major aspects of the cruiser segment of motorcycle culture is customization. Bike riders want to personalize their bikes to suit their style and improve bike performance. As a relatively new model, the Royal Enfield Cruiser 650 begs the question of customization. This covers whether or not aftermarket parts are available, how easily the parts can be modded, and what types of modifications may effect the bike’s performance and warranty. But some enthusiasts are saying its the simplicity of the Royal Enfield bikes that makes them ideal for customization and that other brands have an abundance of aftermarket options. It also covers the fine line between keeping the bike classic and modern.
