2 Enduro ESA The R 1200 GS and GS Adventure model, was face lifted and technically improved in The Enduro ESA was launched, as a factory option. To switch between the spring preload settings below, engine must idle and speed = 0 km/h Change by push ESA button long time, Comfort, Normal, Sport (damping levels) can be changed while riding, by a short push on the button!

6 Öhlins Racing BM 670 ESA replacement system. EC-Adjustment instruction: There are 3 different driving modes available for normal roads and different load conditions:

7 Öhlins Racing BM 670 P ESA replacement system. Pre set EC-Adjuster positions:

8 Öhlins Racing BM 670 ESA replacement system. EC-Adjustment instruction: There are 2 different driving modes available for bad roads and terrain:

9 Öhlins Racing BM 670 P ESA replacement system. Pre set EC-Adjuster positions:

10 The Öhlins TTX-EC system has 4 damping adjusters. The standard enduro-ESA has 2, one front and one rear. –This improves how precise you can control the level of compression and rebound damping for each riding mode. 2 new valves, damping pistons, has been developed for this project. We have implemented an intelligent Smart EC function in the street comfort damping mode that adapts the damping level to the vehichle speed. We have chosen to exclude the EC front pre-load adjuster, that is mainly used to get more ground clearance for rough terrain riding, due to following reasons: –The manual pre-load adjuster on the front T36 is easy to access and adjust. –It saves cost plus weight and our main focus is the hydraulic properties and the electronic control system. Öhlins Racing BM 670 ESA replacement system compared to enduro-ESA

11 When riding in COMFORT mode, the damping level changes automatically to NORMAL mode, when speed is higher than 80 km/h. When speed is higher than 120 km/h, the damping level automatically changes to SPORT mode, but without spring pre-load. When speed is decreasing, the modes switches back again. Note: By adjusting to SPORT setting with the ESA button, there are also a spring preload added. This is a unic Öhlins Racing feature not existing in the ESA system.

12 Spring pre-load adjustment uses very low power consumption, < 2.6 Ampere, (BMW Enduro ESA: BMW Motorrad ESA system Unique features Smart EC function, speed dependent! ( 120 km/h) 4 damping adjusters, instead of 2 on original BMW Enduro ESA Spring pre-load changes with damping levels Significantly improved tyre feeling Full maintenance possibility Familiar Öhlins Racing high end quality and look Future possibility to fit springs with different rate Price level compared to original BMW spare parts is good Individual spare parts available The system is manouvered by BMW ESA button via CAN bus and uses the std BMW dashboard symbols Future upgrade possibilities Patented TTX technology
