As a rider with a height of 5.5 feet, you should find the Suzuki Gixxer 155 to be comfortable to ride. The Gixxer 155 has a seat height of approximately 795 mm (31.3 inches), which is relatively low compared to other sport bikes. This lower seat height allows riders with shorter inseams to comfortably reach the ground when stopped, enhancing stability and confidence.
Additionally, the Gixxer 155 features a well-designed riding position that offers a balance of comfort and sportiness. The handlebars are positioned at a comfortable reach, and the footpegs are set in a mid-mounted position, allowing for a slightly forward-leaning riding posture that is not overly aggressive. This riding position should provide good control and a comfortable stance for riders of varying heights.
It is always recommended to visit a dealership and sit on the bike to gauge how well it fits you and how comfortable you feel. You should check if you can reach the handlebars comfortably and if your feet can comfortably rest on the footpegs.
Taking a test ride, if available, will give you the best idea of how the bike feels and performs for your specific height and comfort requirements.
