The Ohlins BM489 STX 46 Blackline rear shock absorber is designed for BMW R nineT, R nineT Pure and R nineT Racer models.

Adjustment is provided so you can tailor the feel to your bike and riding conditions.

Ohlins | Made to race, perfected to ride

Part of the STX 46 Blackline family, this rear mono shock is finished to complement vintage-inspired motorcycles while delivering modern suspension behaviour. It’s intended as a direct-fit upgrade for the listed BMW R nineT variants.

Shock design & features

  • Rear mono shock configuration for the BMW R nineT platform
  • Ohlins STX 46 Blackline construction and finish
  • Oil/gas separated shock architecture (not an emulsion design)

Before you install

  • Fitment note: does not fit model year 2021
  • Confirm compatibility with your exact model and year before installation

Serviceability/lifecycle

As with other Ohlins road shocks, routine servicing helps maintain damping consistency and seal life over time. Service intervals depend on use, kilometres and conditions.

Is it right for you?

If you want a rear shock with quality damping and the ability to tune rebound and preload, the BM489 is a suitable option for the specified R nineT models. If you require compression damping adjustment, this model is not configured with that feature.
