The Bajaj Dominar 400 stands out as a strong contender among the options mentioned, particularly for those looking for a powerful and feature-rich touring bike. Here are some key reasons why it might be considered the best: - **Engine Performance**: The Dominar 400 is powered by a 373.3 cc liquid-cooled, single-cylinder engine that produces 40 PS of power at 8800 rpm and 35 Nm of torque at 6500 rpm, making it one of the most powerful in its segment. - **Transmission and Gearbox**: It features a 6-speed gearbox with a slipper clutch, which enhances gear shifting and reduces the impact of engine braking, making it suitable for both city riding and long tours. - **Braking and Safety**: The bike is equipped with dual-channel ABS, a 320 mm front disc brake, and a 230 mm rear disc brake, ensuring robust braking performance. It also features a full LED headlamp with auto headlamp on, which is beneficial for night riding. - **Comfort and Touring Capabilities**: The Dominar 400 has an upright riding stance, multi-step adjustable mono shock, and USD forks, which provide comfort and stability during long rides. It also comes with touring accessories like a tall windscreen, hand guards, and bungee straps for luggage. - **Fuel Efficiency**: With a claimed mileage of 27-30 kmpl, it offers a good balance between power and fuel efficiency. In comparison, the Royal Enfield Himalayan is more off-road focused, the Classic 350 is a retro-style cruiser with less power, and the Yamaha MT-15 Version 2.0 is a naked sport bike with a different riding dynamics. Therefore, for those seeking a powerful, feature-rich, and comfortable touring bike, the Bajaj Dominar 400 is likely the best choice.
