Ohlins BM 509 46ER Emulsion Rear Shock Absorber for Motorcycles

The Öhlins BM 509 46ER is a high-performance emulsion-style rear shock absorber designed for small, lightweight motorcycles where packaging space is at a premium. Built around a 46mm piston diameter, this shock delivers the precise, consistent damping control that Öhlins is world-renowned for, in a compact and lightweight package.

Unlike pressurized twin-tube designs, the 46ER uses an emulsion design where oil and gas are mixed within the shock body. This straightforward construction reduces overall size and weight, making it an ideal solution for smaller displacement bikes and tight chassis configurations without sacrificing damping performance.

Key Features:

• 46mm shock piston diameter for responsive, consistent damping force
• Emulsion-style construction — oil and gas mixed in the shock body for a compact, lightweight design
• Adjustable rebound damping — allows riders to fine-tune shock behavior to suit riding style and conditions
• Optimized for small, lightweight motorcycles where space and weight are critical factors
• Engineered and manufactured by Öhlins, a global leader in suspension technology

The Öhlins BM 509 46ER is a direct upgrade over stock suspension components, delivering improved handling, stability, and rider confidence. Whether for street or track use, this shock absorber provides the performance tuning capability expected from the Öhlins brand.
