Yes, a person who is 5'6" can comfortably ride a Royal Enfield Classic 350. The Royal Enfield Classic 350 has a seat height of around 800 mm (31.5 inches), which is relatively low compared to some other motorcycles. This makes it accessible for riders with varying heights, including those who are 5'6" or shorter.
The Classic 350 has a relatively upright riding position, which can provide good visibility and comfort for riders of different sizes. However, it's always recommended to visit a Royal Enfield dealership or showroom and sit on the motorcycle to assess your personal comfort and reach. A test ride can help you evaluate the bike's ergonomics and determine if it suits your specific height and riding style.
Furthermore, it's worth noting that modifying the seat or suspension can also help customize the fit of the motorcycle to better suit your height and preferences. If you have any concerns, discussing them with a Royal Enfield representative or consulting with a motorcycle customization specialist can provide valuable insights and potential solutions.
