What’s the difference between an Inertia Dyno and an Eddy Current Load Dyno?

Inertia Dyno: Calculates power by measuring how quickly the vehicle can accelerate a fixed roller. It’s simple, cost-effective, and ideal for motorcycles or basic power runs.

Eddy Current Dyno: Uses an eddy current brake to apply adjustable load, allowing steady-state, fixed RPM, and advanced tuning. Perfect for precise ECU calibration and repeatable testing.

In short:

Inertia dynos are great for basic testing, while eddy current dynos are built for professional tuning and control.
