BMW ESA products - Tractive Suspension

The Tractive R&D team in their WP past developed BMW ESAI and ESAII. Tractive also has developed dynamic ESA solutions for several high-end powersport brands worldwide. So we consider ourselves quite experienced in electronic adjustable suspension and certainly specialised in BMW electronic suspension from 2005 till now. Suspension service companies can become Tractive dealers and order the technical parts needed for ESA1, ESA2 or dynamic ESA replacement and service. For example Beemershop USA and ESARepair in the Netherlands.

Most ESA shock absorbers consist of
– a damper with adjustable damping by a stepper motor or solenoid valve
– a spring
– a spring preload (ESAI EPA) or spring rate adjuster, mostly electronic, mostly only for the rear shock.
There are several reasons to use our ESA products (pls check video for detailed explanation):
1. For new suspension make ride height or spring rate customer specific. Tractive Shocks come in different ride height and with a range of springs. At the same time they are fully serviceable and tuneable.
2. Replace worn suspension. After some use the stock suspension slowly degrades or becomes dysfunctional (leaking, not functioning). The Tractive shocks come with a heavy duty design for serious loading; 16mm induction hardened CrMo piston rods for increased durability and the electronic adjustment is as good as indestructible
3. Improve ride quality
The Tractive shocks outperform the stock shocks in comfort, but also in handling. This is due to the specific damping setup and the electronic components used. For ESAI and ESAII we use the most reliable stepper motor, for dynamic ESA the most stable and fastest valve on the market
4. The Tractive BMW ESA shocks as described on this page do not have the most extreme offroad properties. But in the TT Adventure line there is a full line Plug&Play shock absorbers with extra canister and aluminum shock absorber housing for optimal thermal stability.
A suspension service company or an experienced BMW dealer mostly has the tools to disassemble the stock shock absorber. It is a relatively simple operation as shown in this conversion video . In below picture is shown how a BMW R1200GS 13- shock is being replaced with a spring fitting to the weight of the rider and 25mm lower rideheight.
