Royal Enfield’s new bullet500 offers vintage styling and ride quality with modern parts. BUSINESS LINE royal enfield’s new bullet 500 uses the same 500cc unit construction engine as in classic and Thunderbirds models, but uses a carburetor instead of an electronix fuel injector.this bike is one of the powerfull bike I have ever seen.it is very easy to start as electric start is given for starting the bike. I like it very much.
