Ohlins BM 503 46ER Emulsion Rear Shock Absorber for Motorcycles

The Öhlins BM 503 46ER is a high-performance emulsion-style rear shock absorber engineered for small, lightweight motorcycles where packaging space is at a premium. Designed and manufactured by Öhlins — the world-renowned Swedish suspension specialist — this shock delivers a significant upgrade over stock OEM dampers in both ride quality and handling precision.

The 46ER designation refers to the shock's 46mm piston diameter, which provides a broad, consistent damping force across a wide range of riding conditions. The emulsion design blends oil and pressurized gas within a single shock body, eliminating the need for a remote reservoir and making it an ideal solution for bikes with tight rear-end clearances.

Key Features:

• 46mm shock piston diameter for strong, consistent damping performance
• Emulsion-style construction — oil and gas mixed within the shock body for a compact, reservoir-free design
• Adjustable rebound damping — allows riders to fine-tune shock behavior to suit riding style and conditions
• Compact form factor — purpose-built for small, lightweight motorcycles with limited suspension space
• Öhlins quality construction — premium Swedish engineering with motorsport-derived technology

The Öhlins BM 503 is a direct-fit performance upgrade that brings race-inspired suspension technology to street and off-road riding. Its straightforward adjustability makes it accessible for riders of all skill levels looking to improve handling, stability, and rider confidence.
