Ohlins BM051 STX46 Adventure S46DR1 Rear Shock Absorber 495mm

The Öhlins BM051 is a STX 46 Adventure S46DR1 rear shock absorber engineered as a direct-fit performance upgrade for BMW R-series GS motorcycles. With a 495mm extended length, this shock is purpose-built to deliver superior ride quality and handling confidence on both road and off-road terrain.

At the heart of the BM051 is Öhlins' proven monotube, high-pressure gas design featuring a large 46mm main piston and an internal gas reservoir integrated within the main shock body. This construction eliminates oil aeration and delivers consistent, fade-free damping performance across a wide range of riding conditions.

Key Features:

• 46mm main piston for precise, responsive damping control
• Monotube high-pressure gas construction with internal reservoir for consistent performance
• Adjustable rebound damping via adjuster wheel above the end eye
• Spring preload adjustment for rider weight and load customization
• 495mm shock length engineered for correct geometry on BMW GS applications
• 100% rebuildable — reshimmable and fully overhaulable for long service life
• Developed from the knowledge of top factory race teams worldwide
• Direct OEM replacement fitment — no modifications required

The Öhlins BM051 is the definitive suspension upgrade for BMW R80GS and R100GS adventure riders seeking improved handling, plushness, and adjustability over the stock shock. Part number cross-references: S46DR1, BM 051.
