Öhlins NIX 30 Cartridge Kit FGK 221 for Suzuki GSX-R 1000 (2012–2023)

If you want noticeably better fork behaviour on your GSX-R 1000 without the hassle of a full suspension overhaul, the Öhlins NIX 30 Cartridge Kit FGK 221 is the most practical upgrade available. Designed specifically for the Suzuki GSX-R 1000 from 2012 through 2023, it transforms the stock fork into a fully adjustable, performance-calibrated unit that rewards everyday road riding just as much as the occasional track day.

Key Features

• 30 mm cartridge system delivers a substantial improvement in fork stability and damping consistency over the stock internals
• Compression damping and its adjuster are housed in the left fork leg, while rebound damping and its adjuster sit in the right leg — keeping each function clearly separated and easy to tune
• All adjustments, including spring preload, are made at the fork cap, so you can fine-tune the setup without removing the fork
• 120 mm stroke matched precisely to the GSX-R 1000 fork travel for accurate damping control throughout the full range of movement
• Compatible springs from the Öhlins 08790 series can be ordered separately, allowing you to tailor the spring rate to your weight and riding style
• Installation guide included; fitting by an authorised Öhlins Service Centre is recommended for optimal results

Performance on Road and Track

The NIX 30 cartridge design is at the heart of what makes this kit so versatile. On public roads, the improved damping smooths out braking dive and reduces the unsettled feel that the GSX-R 1000's standard fork can exhibit under hard deceleration. On track, the separation of compression and rebound circuits means you can dial in each independently — tightening compression for high-speed stability through fast corners while keeping rebound soft enough to maintain contact over kerbs and surface changes. The result is a fork that is genuinely adjustable to suit the rider rather than a one-size compromise.

Installation and Setup

The FGK 221 cartridge kit is engineered as a direct-fit upgrade for the GSX-R 1000 (2012–2023) and arrives with a detailed installation guide. Because precise oil volume and preload setup significantly affect the final performance, Öhlins recommends fitting by an authorised service centre. Springs from the Öhlins 08790 series must be ordered separately — this allows you to specify the correct rate for your riding weight and intended use rather than accepting a generic spring that may not suit you.
