Ohlins BM 679 TTX GP Shock Absorber for BMW Motorcycles

The Öhlins BM 679 TTX Shock Absorber represents the pinnacle of suspension engineering, born from over three decades of world championship road racing and more than 100 World titles. Designed for the performance-minded rider, the TTX (Twin Tube X) platform delivers unmatched adjustability, consistency, and damping precision for both track and street applications.

Advanced TTX Damping Technology:

• Independent high- and low-speed compression and rebound damping — all four adjustment circuits operate independently for maximum tuning flexibility
• Wide adjustment range with equal force increments throughout, allowing the shape of the damping curve itself to be modified to suit any track or riding condition
• All preload and rebound adjustments act directly on damping oil flow through the piston — not on the shock piston rod or oil displacement volume — for precise, repeatable results
• Unique compression damping design: compression force is generated by an increase in pressure on the compression side of the piston, rather than a pressure drop on the rebound side as found in conventional shocks
• This approach drastically reduces cavitation and eliminates the need for high gas pressure in the reservoir, keeping internal pressures to a minimum
• Low internal pressure yields excellent suspension response even under short-stroke, high-force conditions

Key Specifications & Features:

• 36mm shock piston for high-flow damping performance
• Piggyback-type remote reservoir for improved shock oil cooling, delivering more consistent damping and extended damper service life
• Integrated remote hydraulic spring preload adjuster for convenient, on-the-fly spring preload changes
• TTX twin-tube architecture maintains minimum internal pressure for ultra-sensitive response
• Race-proven construction built to Öhlins' motorsport-grade standards

The Öhlins BM 679 is engineered for BMW motorcycle platforms, offering a direct-fit upgrade that brings genuine World Superbike and MotoGP-derived suspension technology to your machine. Whether you're chasing lap times or perfecting your street setup, the BM 679 delivers the adjustability and consistency that has made Öhlins the benchmark in performance suspension.
