What does IMU mean?
An Inertial Measurement Unit (IMU) is a sensor package that measures a motorcycle's motion in multiple axes — typically pitch, roll, yaw and sometimes lateral acceleration. Modern IMUs used in motorcycles measure lean angle, pitch angle and angular rates to feed data to rider assistance systems.
With IMU data, systems like cornering ABS, cornering traction control and wheelie control can be made lean-angle sensitive — meaning they respond differently depending on how far the bike is leaned over. This is critical for safe operation: standard ABS applied at full lean can cause a highside, whereas cornering ABS adjusts braking force to keep the bike stable during cornering.
How riders should use this term
Motorcycle terms are most useful when they help you understand real riding behavior. When you see IMU on a spec page, treat it as one part of the full motorcycle package, not as a number or feature to judge alone.
- Compare the term against the motorcycle category and intended use.
- Check related specs such as weight, engine size, seat height, braking system and suspension.
- Use the comparison tool if two bikes look similar on paper.

Why is IMU important when comparing motorcycles?
It helps riders understand how a motorcycle may feel, perform or behave in real use. The exact importance depends on the bike category and the rider's purpose.
