Ohlins BM 677 TTX GP Shock Absorber for BMW Motorcycles

The Ohlins BM 677 TTX Shock Absorber represents the pinnacle of Öhlins suspension engineering, born from over three decades of World Championship road racing success and more than 100 World Championship titles. This premium rear shock delivers race-proven performance for demanding riders who refuse to compromise.

Advanced Damping Technology:

• Independent high- and low-speed compression and rebound damping — all four circuits are fully independent, offering an exceptionally wide adjustment range with equal force increments throughout
• The shape of the damping curve itself can be tuned to suit specific track types, riding styles, and conditions
• 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 tuning

TTX (Twin Tube X) Compression Design:

• Unlike conventional shocks, compression damping force is generated by an increase in pressure on the compression side of the piston — not by a pressure drop on the rebound side
• This unique design dramatically reduces cavitation and eliminates the need for high gas pressure in the reservoir, keeping internal shock pressures at a minimum
• Lower internal pressures translate to superior suspension response, even under short-stroke and high-force conditions

Key Features:

• 36mm shock piston for exceptional damping control and consistency
• Piggyback-style reservoir provides enhanced oil cooling for more consistent damping performance and extended damper service life
• Integrated remote hydraulic spring preload adjuster for on-the-fly ride height and load adjustments
• Race-derived construction built to withstand the rigors of both track and aggressive street riding

The Ohlins BM 677 TTX is engineered for BMW motorcycle applications and delivers the same championship-level suspension performance trusted by professional racers worldwide. Whether on the track or carving mountain roads, this shock absorber sets the standard for precision, adjustability, and long-term reliability.
