Ohlins BM317 STX46 Street Rear Shock Absorber for BMW R 80 GS

The Öhlins BM317 is a premium STX46 Street rear shock absorber engineered specifically for the BMW R 80 GS. Built on Öhlins' legendary monotube platform, this shock delivers a significant suspension upgrade over the stock unit, offering precise damping control and improved ride quality for both street and light adventure use.

The STX46 Street series is built around a 46mm main piston with a high-pressure monotube gas design and an external piggyback reservoir. Rebound damping is externally adjustable via a dial above the end eye, and compression damping is independently adjustable at the reservoir — allowing riders to fine-tune suspension response to match their riding style and load. An adjustable-length body and a hose-mounted hydraulic spring preload adjuster provide additional setup flexibility to dial in ride height and handling balance.

Key Features:

• STX46 Street platform — type code S46PR1C1LS
• Large 46mm piston diameter for superior damping control
• Monotube high-pressure gas design with external piggyback reservoir
• Externally adjustable rebound damping (adjuster wheel above end eye)

Öhlins shocks are developed from knowledge gained through decades of top-level factory racing programs worldwide. Every unit is individually tested and valved to ensure optimal performance for the specific application. The BM317 is a direct-fit, drop-in upgrade that transforms suspension feel, providing improved stability, cornering confidence, and ride comfort over the factory shock.
