Yamaha FJ-09/MT-09/Tracer 900 (GT) Seat Slope Mod


Most anyone who rides on a Yamaha FJ-09 / FZ-09 (MY ’15-’17), MT-09 / Tracer 900 (MY ’18 – ’20) knows the seat slopes forward aggressively.  The stock seat position pushes you into the tank and on long rides that gets exhausting.  This product is a more elegant and simple solution that results in a neutral seating position with minimal impact on seat height.  This uses all stock hardware and is completely reversable with no permeant changes done to the bike.

Most anyone who rides on a Yamaha FJ-09, FZ-09, MT-09 or Tracer 900 knows the seat slopes forward aggressively.  The stock seat position pushes you into the tank and on long rides that gets exhausting.

This setup raises the forward mount of the seat up by ~6 -7mm(depending on Std or Comfort Seat) and leaves the rear at the same low setting.  This results in a much more neutral riding position with little impact on actual seat height.  This will also work with the seat in the upper position as well.   All stock mounting hardware is used and is completely reversable with no permanent changes done to the bike.  

The setup uses removable pads that go under the front feet of the seat, and a spacer/offset bushings to raise the mount without moving the tank mounting position excessively.

Compatible with:

  • Front OEM stock and Yamaha Comfort seat for Yamaha FJ-09, FZ-09 (’15-’17) and  MT-09,  Tracer 900,  and 900 GT (’18 – 20) seat.   In the upper or lower height position. (Update 10/19/21 – ’15-’17 MY FJ-09 and FZ-09 verified to fit!)
  • Customer feedback and some other testing shows this should work for most aftermarket upgrade seats as long as they use the stock seat base tray (where the fuzzy velcro goes). This is not guaranteed due to the wide variety of aftermarket seats, but customers with ‘Bagster’ brand, and ‘Sargent’ aftermarket seats have had success.


Made with the same high end and very temperature stable Nylon Carbon fiber a lot of my products are made with.   The TPU is super soft TPU to ensure the vibration isolation of the tank mounts is maintained.

Included with the kit: (Note some pics are from preproduction testing so specs have changed based on the results)

  • 2x offset grommets for the rear mount of the fuel tank to the mounting plate, this allows the bracket to be moved upward without changing the tank angle much.  Printed in TPU rubber to retain the vibration isolation of the stock setup.  The stock spacer/washers slide into the TPU like the original bushings.
  • 1x Carbon Fiber Nylon 6mm shim that goes under the seat forward mounting plate.
  • 2x Carbon Fiber Nylon 6mm forward seat shim plates.   Attached via Industrial Velcro to give the easy ability to remove or change easily. (the shim is closer to 7mm with Velcro accounted for, preloading the front feet of the seat)
  • 4x Laser cut Industrial velcro pads included in the package for mounting the foot pads.
