Royal Enfield Thunderbird 350 Highlights

25 October 2017: The Royal Enfield Thunderbird 350 is a well-known name in the tribe of laid-back cruisers in India. A comfortable riding position, commanding road presence and a number of interesting features like the big 20-litre fuel tank make the Thunderbird 350 a well-rounded package for long tours. Powering the Thunderbird 350 is the same 346cc, single cylinder engine that runs the company’s Bullet 350 and Classic 350 models. The carburetted motor churns out respective power and torque figures of 20bhp @ 5250rpm and 28Nm @ 4000rpm. The motorcycle gets its stopping power with the help of a 280mm disc brake up front that couples with a 240mm disc brake at the rear. It has a claimed mileage of 40kmpl and a top speed of 107kmph (claimed). The salient features of the Thunderbird 350 include a rounded headlamp with curvy LED Daytime Running Light (DRL), pillion backrest to offer optimum comfort and unique glittery body colours. You can choose from the five colour options available: Stone, Marine, Lightning, Flicker and Asphalt. The Royal Enfield Thunderbird 350 can be yours at Rs 1,62,588 (On road, Delhi) and primarily competes against the likes of Bajaj Dominar 400, Royal Enfield Classic 350 and the UM Renegade Commando.
