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

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

Step 2 — Grab the file straight from disk

Fastest path: Race Studio 3 saves downloaded files at a fixed location, organized by date. No need to open the software to export — you can take the .xrk directly.

Windows: C:\AIM_SPORT\RaceStudio3\user\data\[date]\
- [date] is the track-day date subfolder, e.g. 2026-06-22
- Each session of the day is a .xrk file

Tip: paste the path straight into the Windows Explorer address bar to jump there in one click.

Alternative if Race Studio 3 is already open: right-click the session → Open File Location.

Step 3 — Import into Brake Point

Log in to app.brakepoint.io
Click Import a session
Select your .xrk file
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. Once Race Studio 3 has downloaded the session, the file is immediately available in C:\AIM_SPORT\RaceStudio3\user\data\[date]\ — you no longer need the software to import it into Brake Point.
