Description
Fits all years of Yamaha MT-09 2021 – 2025+
After the success of the seat slope mod for the ’15 -’20 FZ/FJ/MT/Tracers I worked with some members of the community to design a solution for the 2021+ MT-09 Seats. The MT-09s suffer from the same forward slant as most of the other CP3 engined bikes. This kit has been tested over 2 years before coming to market.- JK3D.us Adjustable 6+2 mm Shim – Some riders prefer some forward lean on the seat for most spirted riding, and then a flatter seat for longer rides. This kit will allow fairly easy adjustments based on riding preference.

Compatible with:
- Front OEM stock and Yamaha Comfort seat for the 2021+ Yamaha MT-09 models (including SP). (Should work with most aftermarket seats that use the Yamaha Seat Pan) Works with the seat in the factory low or high positions.
- Not Compatible with Tracer 9 models
Materials:
Frame Shims- Industrial Grade Carbon Fiber PA12 Nylon – High temperature, high strength, high durability and chemically resistant material.
Rubber Bushings- High temperature Easton 85A softness TPU rubber. This is to ensure the vibration isolation of the tank mounts is maintained.
Included with the kit:
- 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 rear height more than 3 or 4mm, a height change that is almost not visible and looks natural. 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.
- Seat Frame Brace Shims: Adjustable Kit: 2x 6mm Pads, and 2x 2mm shims for adjustability
- 4x 6mm Zinc Plated Alloy Steel bolts (Class 10.9)
- 8x 6mm fender Washers
Tools required to install:
- 4mm Hex Wrench
- 10mm socket/wrench
- Blue Thread lock compound
- Torque Wrench (12Nm for the main bolts, 7Nm for the fuel tank bolts)
