The Ohlins BI318 STX 36 Twin is a rear shock unit for Bimota SB 6 and SB 7 applications. Built around Ohlins’ STX architecture, it focuses on controlled damping behaviour and repeatability in demanding road and track conditions. It is designed to deliver clear chassis feedback and stable support when riding hard.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong racing background and then refined for real-world rideability. The aim is predictable behaviour at the limit, without compromising control and feel. This unit follows that approach with a robust, serviceable design.

Who this shock is for

  • Riders who want more consistent rear-end control and feedback than a basic OE-style shock.
  • Owners using their Bimota SB 6 or SB 7 for spirited road riding and regular track days.
  • Set-up focused riders who value adjustability to suit tyre choice, riding style, and conditions.

Shock design & features

This is a gas-pressurised shock design intended to maintain damping consistency during extended, hard use. The STX 36 Twin family is engineered to provide stable damping behaviour and predictable response through the stroke. It is built as a dedicated rear unit for this fitment.

Tuning controls

Separate damping circuits are provided for compression and rebound adjustment. This allows you to fine-tune support under acceleration/braking and manage how quickly the rear returns after bumps and load changes, helping balance traction, stability, and feel.

Before you install

  • Confirm the motorcycle model and year match the intended fitment (Bimota SB 6 / SB 7) before installation.
  • Set sag and ride height carefully after fitting to ensure the damping adjustments can be used effectively.
  • If your bike has been modified (linkages, swingarm, or geometry changes), allow time for additional setup and tuning.

Serviceability / lifecycle

Like all performance shocks, the BI318 benefits from routine inspection and periodic servicing to keep damping consistent and protect internal components. Keeping the unit maintained also ensures adjustments remain responsive and predictable over time.

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.
