Yes, it is generally possible to ride a Suzuki Gixxer SF with a height of 5'6" (167 cm). The Gixxer SF has a seat height of approximately 795 mm (31.3 inches), which is considered relatively low for a sporty motorcycle. This lower seat height makes it more accessible for riders with average height or shorter stature.
With a seat height of 795 mm, most riders with a height of 5'6" should be able to comfortably reach the ground when seated on the Gixxer SF. However, it's important to note that individual body proportions can vary, and personal comfort can be subjective. It's always recommended to visit a Suzuki dealership or a motorcycle showroom to physically sit on the bike and assess how well it fits you.
During a test ride, ensure that you can comfortably place your feet flat on the ground and reach the handlebars without straining or feeling uncomfortable. The Gixxer SF has a relatively sporty riding position with forward-set footpegs and clip-on handlebars, which may require some adjustment depending on your riding style and preferences.
If you have the opportunity, it's advisable to test ride the bike or at least sit on it to gauge your comfort level before making a purchasing decision. Additionally, you may consider getting the seat height adjusted or exploring aftermarket options for lowering the seat height further, if required, to enhance your confidence and comfort while riding.
