The Ohlins FGK231 NIX 30 fork cartridge kit is designed to refine the front-end control and feel of the BMW R nineT. It focuses on improving stability under braking and delivering clearer feedback through the mid-corner phase. With independent damping adjusters, it allows a more deliberate setup for your riding conditions.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension expertise, the FGK231 cartridge kit is built to provide consistent damping behaviour and predictable front-end response. It is intended as a performance-focused internal upgrade to the standard fork arrangement.

Who this cartridge kit is for

  • BMW R nineT riders looking for improved front-end feedback and confidence
  • Street riders who want a more controlled feel during braking and cornering
  • Riders who want tuning capability without changing the complete fork assembly

Shock design & features

  • NIX 30 fork cartridge design
  • High-quality internal components for durable, consistent performance over time
  • Improved braking stability and mid-corner feel compared with a basic fork setup

Tuning controls

  • Separate compression adjustment
  • Separate rebound adjustment
  • Designed to make fine changes to damping feel and control during riding

Before you install

  • Confirm compatibility with your exact BMW R nineT model and year before fitting
  • Professional installation is recommended to ensure correct assembly and setup
  • After installation, allow time to adjust compression and rebound to your preference

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
