Yes, it is generally possible to remove the pillion seat from a Suzuki Gixxer 150 motorcycle. The pillion seat is designed to accommodate a passenger, but if you prefer to ride solo and want to remove the seat, it can usually be done.
The specific process for removing the pillion seat may vary slightly depending on the model year and design of the Gixxer 150. However, in most cases, you will need to locate and remove the bolts or fasteners that secure the pillion seat to the motorcycle frame.
To ensure you are removing the seat correctly and safely, I recommend consulting the owner's manual or reaching out to a Suzuki authorized service center for guidance. They can provide you with detailed instructions or assist you with the process if needed.
