Royalenfield is the best bitullet bike in the worls as compared to othe normal bikes or bullet bikes.it comes with 3 types of cc engine.they are 350 cc, 500cc, 410 cc engines.models are electra, classic, thunderbird, continetol, himalayan.in my opinion electra model is the best mode lbecause it gives the best milage with stylish look like royality.it gives fifty plus milage in national highway & in city u can measure it to 45km per litre.my uncle is the owner of vaishnavi automobile in odisha so I knew well information about royalenfield bikes.
