The Ohlins STX 46 Street rear shock is a purpose-built replacement for Buell XB12R and XB9R Firebolt models, aimed at improving control and feedback in real-world road riding. Built around Ohlins damping know-how, it is designed to deliver consistent performance through changing road conditions and sustained use. This unit uses a gas-pressurised, oil/gas separated design to help maintain stable damping behaviour.

Ohlins | Made to race, perfected to ride

Ohlins street suspension focuses on predictable chassis behaviour and clear tyre feedback. The STX 46 Street platform is intended for riders who want a more controlled, confidence-building ride without losing practicality for everyday use.

Who this shock is for

• Owners of Buell XB12R Firebolt and XB9R Firebolt looking to refresh or upgrade rear suspension performance
• Riders who value stability under braking and consistent support through corners
• Street-focused riders wanting adjustable damping to suit road pace, load, and tyre choice

Shock design & features

This is a monotube-style rear shock with separated oil and gas, using internal pressurisation to support consistent damping behaviour. The STX 46 Street architecture is designed to give controlled movement and improved composure over varied road surfaces while maintaining clear feedback at the rear tyre.

Tuning controls

Adjustability is provided for rebound damping and compression damping, allowing you to tune how the shock returns after bumps and how it resists compression under load. These adjustments are intended to help balance comfort, grip, and chassis stability for your roads and riding style.

Before you install

This unit is made as a direct-fit rear shock for the listed Buell models. After installation, set sag and confirm clearance through suspension travel, then fine-tune rebound and compression to suit your tyres, typical roads, and load (solo, passenger, luggage).

Serviceability/lifecycle

As with all performance dampers, periodic servicing helps keep damping consistent and reduces wear over time. Regular inspection and timely oil and seal maintenance will support long-term performance, especially if the bike is used frequently or in harsh conditions.
