///Dynostar D70

Dynostar D70

The Ultimate Motorcycle dyno

The Dynostar Model 70 is the ultimate tool for tuning and diagnostic activities. Many reputable companies in the trade, including 6-times World Champion Ten Kate Honda, have already discovered the quality of the Dynostar Model 70.

The Dynostar Model 70 is available as “above ground” model and as a “pit” model. The Dynostar Model 70 is equipped with a roller with high mass inertia, and can absorb dynamic power up to 465 kW and speeds up to 325 km/h.

D70 Triple Inertia

Product information Dynostar Model 70 (pit model and above ground model) 

The powerful, air-cooled eddy current brake allows the dynamometer to absorb power up to 355 kW (with cold eddy current brake). For anyone professionally testing and tuning very high power motorbikes, the optional tungsten carbide anti-slip coating provides the answer. With this option, wheel slip is a thing of the past.
The Dynostar Model 70 is a highly accurate dynamometer. The dynamometer is also vibration-free, because the roller and retarder are mounted on the same shaft and are dynamically balanced.

Product information Dynostar Model 70 Harley-Davidson edition

The Dynostar Model 70 Harley-Davidson edition is the ultimate diagnosis and tuning tool for the Harley-Davidson workshop. The dynamometer is technically identical to the Dynostar Model 70, but painted in original Harley-Davidson colours so it fits perfectly into the look and feel of your Harley-Davidson workshops! Additional we have the ability to connect our software with the Screaming Eagle Tuner software, the motorcycle itself and read data in real time!

We are also willing to discuss another colour scheme to match your Corporate Identity.
