To bring the pillion seat of your Honda CB Hornet 160R to the same level as the rider's seat, you may need to make modifications to the seat or seek assistance from a professional. Here are a few options you can consider:
Seat modification: You can visit a local seat upholstery shop or a professional bike customizer who can modify the seat to your desired specifications. They can reshape the pillion seat by adding or removing padding to make it even with the rider's seat.
Seat replacement: Another option is to replace the existing seat with an aftermarket seat that has a flatter design or adjustable height. There are various aftermarket seat options available that can provide a more uniform seating surface.
Consult a professional: If you are unsure about making modifications yourself, it is advisable to consult a professional motorcycle mechanic or technician who has experience in customizing bike seats. They can assess your specific requirements and suggest appropriate solutions.
It's important to note that modifying the seat may impact the comfort and ergonomics of the bike, so it's recommended to consult an expert and test the modified seat before making any permanent changes.
