ABS Pro

The procedure for retrofitting ABS Pro on compatible BMW Motorrad bikes involves a combination of potential hardware installation and specialized software coding. Unlike a simple software flash, ABS Pro relies on lean angle sensors, and its retrofit requires enabling these features and altering the ABS control strategy to use that data. 

What is ABS Pro?

ABS Pro is a cornering-optimized anti-lock braking system that uses lean angle data from existing sensors on the motorcycle (e.g., the Inertial Measurement Unit, or IMU). By monitoring the bike's banking angle, ABS Pro can precisely adapt its braking intervention to prevent wheel lock-up and sudden righting moments while braking in a turn. This reduces the risk of falling in an emergency braking situation while cornering. 

Typical retrofit procedure

The complexity of the retrofit varies significantly depending on whether the motorcycle already has the necessary lean angle sensors installed for other systems, such as Dynamic Traction Control (DTC) or Riding Modes Pro. 

Step 1: Pre-installation check

A qualified technician or a specialized service center must first determine if the bike is mechanically equipped for the upgrade. 

• Check for existing hardware: If the motorcycle was factory-equipped with DTC or Riding Modes Pro, it will likely have the required sensors (IMU) already installed. In this case, the retrofit is often a software-only update.

• Missing hardware: If the bike lacks the necessary sensors, the retrofit is more complex and expensive, requiring the installation of the IMU and associated wiring, in addition to the software coding. 

Step 2: Acquire the necessary files

For a successful retrofit, a specific enablement code (FSC) is required. This code is tied to the bike's Vehicle Identification Number (VIN) and is purchased through an authorized BMW Motorrad dealer. 

Step 3: Electronic coding and activation

Once the hardware (if needed) and enablement code are ready, a technician uses specialized diagnostic software to complete the process.

1. Connect diagnostic tool: The technician connects to the motorcycle's ECU via the diagnostic port.

2. Add to Vehicle Order (VO): The ABS Pro feature is added to the bike's vehicle order, a record in the ECU of all installed options.

3. Code the ECU: The ABS control unit is recoded to activate the ABS Pro software. This step incorporates the new functionality and uses the data from the IMU to modulate brake pressure while cornering. 

Step 4: Final checks and calibration

After the coding is complete, the motorcycle is tested to ensure all systems are functioning correctly.

• The system performs a self-test when the ignition is switched on. The ABS indicator light on the dash should turn off once the system confirms that it is operating without faults.

• A test ride may be performed to verify the new ABS Pro functionality. 

Key considerations

• Dealer vs. third-party: While some third-party solutions exist, the most reliable and officially supported method for retrofitting ABS Pro is through an authorized BMW Motorrad dealer. The process requires specific software and codes that are typically only available through official channels.

• Cost: The price of the retrofit can vary widely depending on whether it requires hardware installation or is a software-only upgrade. A software-only upgrade is significantly cheaper.

• Model compatibility: ABS Pro retrofits were initially released for high-performance bikes like the HP4 and S 1000 RR (model years 2012–2014). Compatibility expanded over time to include other models like the R 1200 GS and K 1600 GT/GTL. It is critical to confirm that your specific model and model year are compatible with the retrofit.
