dynoKRAFT MPS170 Powersports

Mobile engine dynamometer

Universal test system covering various applications.

Features highlight

  • 1700Nm
  • 8.000 RPM
  • adjustable chassis

The dynoKRAFT MPS170 mobile engine dynamometer offer exceptional high measurement precision together with best-in-class DAQ system and high speed Sport Devices PWS-HS eddy current brake power supply.

The dynoKRAFT MPS170 can be used to test internal combustion or even electric engines installed in various sports equipment without the need for expensive engine test bed. Only engine specific adapter plates are required.

It is fully adjustable and can be fitted to most engine stands with affordable clamping system.
Special fixing system for Jetski and Snowmobiles can be supplied on order.

For most applications the dynamometer is supplied with high-flexible TOK torsional clutch. Please fill out the technical questionnaire in “Downloads” section.
