Yes, a person who is 5.7 feet (or approximately 170 cm) tall can ride the Bajaj Pulsar NS200 comfortably. The NS200 has a seat height of around 805 mm (or 31.7 inches), which is relatively accessible for riders of average height.
With a seat height within that range, most riders with a height of 5.7 feet should be able to plant their feet firmly on the ground while seated on the motorcycle, allowing for stability and control at stops or when maneuvering the bike. Additionally, the NS200 has a well-designed riding position that provides a good balance between sportiness and comfort.
It's important to note that individual preferences and body proportions can vary. Some riders may have longer legs or a shorter torso, which can affect their comfort level on specific motorcycles. If possible, I would recommend visiting a dealership or a friend who owns an NS200 and trying it out for yourself to ensure that you feel comfortable and in control while sitting on the bike and reaching the handlebars and foot controls.
Ultimately, the best way to determine if a motorcycle is suitable for your height is to physically sit on it and test it out. That way, you can assess the ergonomics and comfort firsthand and make an informed decision based on your personal experience.
