Description
Given that you’re reading this, you’re probably very well aware that Yamaha took some short cuts with the suspension. The factory-issue forks are adjustable for rebound only, and in stock form, provide very little damping (regardless of whether you own an FZ-09, FJ-09, or XSR900 – they all have their own deficiencies). The good folks at GP Suspension took matters into their own hands and developed a fantastic valving solution specifically for the FZ-09. We custom tailored it to our specifications.
- 20 mm compression valve w/ custom shim stack, optimized bleed port, and check valve assembly.
- 20 mm rebound piston w/ custom shim stack and check valve assembly. Yes, you’ll actually have access to meaningful damping to eliminate the pogo-effect from the factory.
- 8 degree rebound needle to provide better laminar flow characteristics through the rebound bleed and increased adjustability.
- (Optional) SKF ‘Green’ Fork Seals – reduced stiction w/ increased service life
- (Optional) Fork Springs
We pair this kit with fork oil and the market’s only drop-in fork spring (optional), sized for the customer’s weight and riding style. This kit follows the factory’s non-adjustable compression approach, but the results are quite amazing. Even sub-freezing temperatures won’t adversely impact the forks’ performance. You’ll gain increased low-speed rebound/compression damping without an undue increase in high-speed compression. In layman’s terms, less brake dive, no pogo-effect – all without creating harshness. For the money, this kit can’t be beat!
Springs are purchased separately here: Fork Spring Kits. Please contact us for spring rate recommendations!
Also, please be aware that installation instructions are not provided with this kit and technical support is not available for your installation. In short – we can’t see what you’re doing, so make sure you know what you’re in for or find a qualified local shop who can complete the installation for you. However, we also offer a DIY Drop-in Cartridge Kit to ease the installation (click for details).

Wow, what a transformation!!! This kit made my FZ 09 into an entirely new bike. Absolutely no more issues with the soft and spongy factory front forks. I no longer have any of the stock POGO effect. The bike point, plants, and sticks. If you have a 14-16 FZ 09, stop looking for suspension and buy this kit. I promise you that you will be happy.
