The brochure says that the Thunderbird X’s new styling, stand-out paint schemes are coordinated with the seats and the rims. For the first time ever, Royal Enfield bikes will get dual colours with the base colour being black. The engine, exhaust and the alloy wheels are all painted in black, giving a sporty touch to the bike.

The Thunderbird X also gets a few styling changes. There is a new wider handlebar, which is different from the regular Thunderbird. It gets kicked-up footpegs to give that cruiser feel. The grab rails have been redesigned that adds an infinity seat effect to the bike. For the first time, Royal Enfield will offer alloy wheels with a bike. The alloy wheels will get a colour-coordinated reflective sticker too. The model moniker is pasted on the battery and toolbox. It says 350X or 500X depending on the variant with Thunderbird written in small letters below it.

The new bikes are very much inspired by the Harley-Davidson models. They also offer a much relaxed riding posture than the regular Thunderbird. Mechanically, the bikes remain untouched. The 500X will be powered by a single-cylinder, air-cooled 499cc engine that develops a maximum of 27.2 Bhp at 5,250 rpm and 41.3 Nm at 4,000 rpm. The 350X draws power from a single-cylinder, air-cooled 346cc engine that produces a maximum of 19.8 Bhp at 5,250 rpm and peak torque of 28 Nm at 4,000 rpm.

There are standard front and rear disc brakes on both the models. However, the ABS is still absent. The bikes are expected to be Rs. 4,000 – 5,000 more expensive than the regular models.
