Ohlins BM 676 TTX Adventure Rear Shock Absorber for BMW R1200GS

The Öhlins BM 676 is a premium TTX Adventure rear shock absorber engineered to deliver race-proven suspension performance for demanding dual sport and adventure riding. Available in TTX36 and TTX39 configurations, this shock absorber is purpose-built to handle the varying and often unforgiving load conditions of both on- and off-road use, offering a significant upgrade in feedback, control, and comfort over stock suspension.

At the heart of this unit is Öhlins' patented Twin Tube X (TTX) technology, which creates a positive internal pressure balance throughout the shock. Unlike conventional monotube designs where low pressure on the piston's rebound side can cause cavitation, the TTX routes damping oil through the cylinder head and between the inner and outer tubes. This eliminates the risk of cavitation entirely — meaning consistent, reliable damping forces are maintained even under extreme conditions.

Key Features:

• Independent high- and low-speed compression damping adjustment — gold adjuster on TTX36/TTX GP shocks
• Independent rebound damping adjustment — black adjuster on TTX36 shocks, silver on TTX GP shocks
• Wide adjustment range with equal force increments across all settings, including the ability to alter the damping curve shape
• All preload and rebound changes act on damping oil flow through the piston — not on the piston rod or oil displacement volume
• Compression damping generated by increased pressure on the compression side (not a pressure drop on the rebound side), minimizing internal pressure and reducing wear
• External piggyback-style reservoir for improved shock oil cooling and long-term damping consistency
• Hose-mounted hydraulic spring preload adjuster for convenient on-the-fly tuning
• Reinforced cylinders designed for the rigors of dual sport use
• Type Code: T39PR1C1S | Length: 402.5mm | Stroke: 75mm | Fitted Spring: 01103-49

The Öhlins BM 676 brings three decades of world championship racing development to the adventure segment, offering a level of tunability and reliability that serious riders demand. The piggyback reservoir ensures consistent damping oil temperatures across extended rides, while the TTX platform's low internal pressure design delivers exceptional suspension response — even under short stroke, high-force impacts.
