The Avenger 150 is designed primarily for cruising on city streets. The bike has a distinctive appearance thanks to the design, which will draw the attention of onlookers. The handlebars are built to make manoeuvring around the city simple for the rider. The bike's length is 2177 mm, its width is 801 mm, and its height is 1070 mm. The motorcycle has a 1480 mm wheelbase and 169 mm ground clearance. The bike weighs 148 kilogrammes.

The tank shrouds that mimic the fuel tank with the metallic finish on either side are beautiful. From the front, this motorcycle appears to be fairly large and solid. In contrast to the rear side panel, which is available in the motorcycle's colour, the pillion grab-rails, and the rear diamond-cut alloy wheel, the blacked-out side panels and double-barrel exhaust look fantastic in the back. The distinctive Bajaj-style LED tail lamp gracefully finishes the rear.

A fully digital instrument panel, LED headlights, precise LED front and rear indicators, and svelte diamond-cut alloys are all standard on the Dominar 400. In addition, a gear-position indicator is present on this motorbike, although it is inconvenient to use because it is mounted on the fuel tank.

This motorbike has a liquid-cooled 373.2cc engine, dual-channel ABS, and a slipper clutch as far as mechanical components go. On or off the road, the Dominar 400 is a sure-footed, steady motorcycle that is incredibly fun to ride. The Dominar 400 is what it is today, largely thanks to Bajaj's genius in this area.

43 mm front USD forks and a Nitrox Monoshock suspension at the back help to achieve the same results. Despite not entirely looking like one, the Dominar 400 is a highly responsive motorbike because of the strength of the beam perimeter frame, which is combined with the kerb weight of 187 kg.

However, the Dominar 400 may be difficult to manoeuvre and demand more effort in severe off-road circumstances. The wide-set handlebars, which are also comfortable, greatly improve handling.
