The Ohlins BU888 is a rear TTX RT shock absorber built for Buell 1125CR and 1125R fitment. It uses a separated oil and gas design to keep damping consistent as temperatures and workloads change. The TTX layout focuses on stable damping behaviour and predictable chassis support for fast road and track use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing suspension architecture, this unit is intended to provide controlled damping response and clear feedback at the rear tyre. The aim is repeatable performance and confidence when loading the bike through braking, turn-in and corner exit.

Who this shock is for

Riders chasing a more controlled rear end than a standard shock, especially when riding harder on the road or doing regular track work. It suits those who want tuning range to match tyre choice, pace and surface conditions.

Shock design & features

This is a TTX RT rear mono shock with oil and gas separated for consistent damping behaviour. The internal architecture is designed to maintain stability through sustained use and reduce variability as the shock works through repeated high-load events.

Tuning controls

External damping adjustments are provided for both rebound and compression, allowing you to balance support versus grip and refine how the bike reacts to bumps, braking loads and acceleration. A spring preload adjuster is also included to set ride height and sag correctly for rider weight and use.

Before you install

  • Confirm model fitment for Buell 1125CR and 1125R and check overall condition of linkage and mounting hardware before installation.
  • Set sag and preload first, then fine-tune rebound and compression to suit tyres and riding conditions.
  • After initial rides, re-check fasteners and re-evaluate settings once the spring has settled.

Serviceability/lifecycle

As a rebuildable Ohlins unit, the BU888 is intended to be serviced periodically to maintain damping quality and seal reliability. Regular servicing is particularly important if the bike sees frequent track use or harsh conditions.
