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.
