Although Royal Enfield has been selling the Thunderbird in India since the year 2000, it was only by 2009 that the brand updated the motorcycle comprehensively by introducing the 346 cc unit construction engine (UCE) that now powers all their 350cc models.
In October 2012, Royal Enfield launched a facelifted version of the Thunderbird 350, featuring a teardrop shaped fuel tank, digital instruments and fuel gauge and a projector headlamp. Additionally, the motorcycle gets an LED tail light and a few other cosmetic enhancements.
The Thunderbird 350 uses a single cylinder, 4 stroke, Twinspark engine 19.8 bhp of power at 5,250rpm and 28Nm of torque at 4,000rpm. This air cooled unit is mated to a 5-speed gearbox. It has recently been updated with the option of ABS for a very small premium over the standard model.
The Thunderbird 350 is available in five different colours and competes with the Jawa range, UM range, and to some extent, the Bajaj Avenger Cruise 220.
