Royal Enfield displayed the 500cc variant of this bike for the first time at Delhi Auto Expo 2012. Now, they have officially launched this variant and expect the brand Thunderbird to reach new heights of success. The original design of Royal Enfield Thunderbird remains the same. Royal Enfield has made minor changes in this bike which are hard to notice at first glance. The bike lacks visor and cowl and with its upraised handlebar, it looks like a true cruiser bike when seen from the front. It has a circular LED projector type headlight which has never been seen before in any Enfield bike. Tiny round shaped side indicators are placed on the both sides of this headlight. Its hand levers and naked instrument dials are chrome finished. This new variant has beefy front forks which along with its short front fender makes it look macho and aggressive. Royal Enfield Thunderbird 500 is powered by a 499cc single cylinder mill that produces 27.2bhp and 41.3Nm of torque. The engine has been mated to a five-speed sequential gearbox and sends power to the wheel via a chain drive. The bike isn?t impressive when it comes to fuel economy. Expect it to return a mileage of around 25-30km/ltr on highways while these figures get reduced in city traffic. Royal Enfield Thunderbird 500 has a highly cushioned seat which even offers nice under-thigh support. The split seat and rear backrest for pillion rider makes it the most comfortable bike for two people. Royal Enfield Thunderbird 500 is equipped with a vibration free wide and angled handlebar. It gives the most important, cruising feel to the rider. You also get a firm palm grip with high quality of plastic buttons and engine kill switch on its handlebar. Its front-set foot pegs adds to the comfort ability of this bike. The knees always stay free and relaxed. The suspension and braking system of Royal Enfield Thunderbird 500 is specially designed keeping its heavyweight in mind. It sports front telescopic forks of 41mm and twin gas charged rear shock absorbers. The RE Thunderbird 500 is available in three major colours-black, twilight black and a shade called flicker black.
