About Thunderbird 350X

Royal Enfield saw a need in the market for an urban cruiser, and this is the result: the Thunderbird 350X. It gets a similar driveline as the regular Thunderbird 350, but there are a few changes. One, it is available in bright, single-tone colours in the same vein as the Classic Redditch series. The 350X is available in red or white. The handlebar is a flatter, wider one, which should help with manoeuverability in the city. It gets all-black treatment, which extends to the alloy wheels. This is the first time a Royal Enfield has been shipped with alloy wheels and tubeless tyres from the factory. It gets the same 346cc carburetted single-cylinder air-cooled engine from the Thunderbird 350. It generates 19.8bhp and 28Nm and transmits it via a five-speed gearbox. The wheels are a 19-inch front and an 18-inch rear. There are disc brakes at both ends, with a 280mm front disc and a 240mm rear one. ABS is now an option that makes the 350X Rs 6000 dearer. The seat of the Thunderbird 350X has been changed – it is a more modern-looking one. The rider’s seat is wider, and the pillion seat is smaller.

The Royal Enfield Thunderbird 350X competes with the likes of the Bajaj Dominar 400 directly. Bikes like the Yamaha Fazer 25 also cater to a similar audience, although it is a different format of motorcycle.
