dynoKRAFT M120-pro

Entry level motorcycle dynamometer

Best-in-class DAQ system and powerful retarder.

Features highlight

  • 440mm [17,3″] roller
  • 300km/h [186mph]
  • 500HP wheel power
  • ready to use test system

An affordable, feature-rich motorcycle dynamometer for workshops!!!

The dynoKRAFT M120-pro motorcycle dynamometer shares the same frame and design principles of our high-end M200-evo test bench.
It offers exceptional high measurement precision together with best-in-class DAQ system and Software for comprehensive data analysis.

With 1200Nm eddy current brake the M120-pro covers most applications and offers the ability to test up to 500HP (at rear wheel).
The roller diameter of 440mm reduce tire wear drastically and help keeping the tire temperature under control during long test sessions.

The ultra-low roller inertia allows users to dynamically change the engine RPM and limits tire slip.

The dynoKRAFT M120-pro is delivered ready to use with all required components such as computer stand, weather station and loading ramp – just connect any WIndows PC and start working!
