Import your AiM XRK/XRZ files

Prerequisites

• Software: AiM Race Studio 3 (Windows)
• Compatible logger: AiM Solo, Solo 2, EVO4, EVO5, MyChron5
• Output format: .xrk

What is the XRK format?

The XRK format is the native format of AiM loggers. Unlike the CSV export, it contains all raw data recorded by the logger with no loss of precision. This is the recommended format for optimal analysis.

Step 1 — Download the session from the logger

1. Connect your AiM logger to your computer via USB or Wi-Fi
2. Open Race Studio 3
3. Go to Data Download
4. Select the session and click Download

Step 2 — Locate the XRK file

Downloaded sessions are stored by Race Studio 3 in a folder on your computer:

• Windows: C:\Users\[YourName]\Documents\Race Studio\Data\[LoggerName]\
• Each session is a .xrk file

You can also right-click on the session in Race Studio 3 → Open File Location to find the file directly.

Step 3 — Import into Brake Point

1. Log in to app.brakepoint.io
2. Click Import a session
3. Select your .xrk file
4. Brake Point decodes the binary format and extracts all available data

Extracted data

The XRK format typically contains:

• GPS: position, GPS speed, heading
• IMU: lateral and longitudinal accelerations
• ECU (if connected): RPM, gear, throttle position, brake pressure
• GPS Gyro: calculated lean angle (motorcycle)
• Laps: lap markers embedded in the file

XRK vs CSV — Which to choose?

	XRK	CSV
Precision	Full raw data	Limited to exported channels
Ease	Ready-to-use file	Requires manual export
Size	Larger	Lighter
Recommended	Yes	If XRK not available

Our advice: use the .xrk file whenever possible. You don’t need to open Race Studio — download the session and import the file directly into Brake Point.
