The bike features colour-coded stitching on the seat and matching rim stickers.

The Royal Enfield Thunderbird 350X looks more contemporary than the regular variant, and gets alloy wheels wrapped with tubeless tyres for the first time. The seat is also a single-piece ‘Gunslinger’ unit, and along with the flatter handlebars, the riding position is slightly sporty. The UM Renegade Sports S has a design that is reminiscent of the Harley-Davidson Street 750, particularly its café-racer inspired headlight cowl. UM targets urban tourers with the bike. The Sports S also comes with LED light strips below the tank and a USB charging port.
