Of the three bikes you’re deciding between, the Triumph Scrambler 400 X will be the most capable machine in terms of carrying a pillion and covering distances. This is because it is the largest feeling bike here with the best suspension comfort and spacious seats. Its 40hp engine will also give you levels of performance the other two air-cooled 350s won’t be able to match.
However, if you are a relaxed rider, then the Honda CB350 and Royal Enfield Bullet 350 will be right up your alley. Both have smooth, torquey air-cooled engines, wide and spacious seats, and good suspension.
It all comes down to what sort of riding experience you prefer. We would recommend a test ride of each bike with your preferred pillion so you can make a more informed decision.
