D70 – Precision Dyno Testing

The D70 features a high-inertia drum and a rigid tubular steel frame with machined bearing posts for

vibration-free operation. It measures up to 465 kW dynamically and supports speeds up to 325 km/h. Its air-cooled eddy current brake absorbs up to 355 kW. The Tungsten carbide coated drum ensures optimal traction during ridged testing.


D70Ti – Adjustable Inertia for All Bikes

The D70Ti offers the same precision as the D70 but includes a three-piece drum, allowing operators to adjust drum inertia to the motorcycle tested. From small bikes to high-powered superbikes, the D70Ti delivers versatile, professional-grade testing.

D70-E - Electric Edition – Drive Cycle Ready

The D70-E is designed for modern testing requirements. It supports WLTP, NEDC, and other drive cycles via Dynostar ADS software. With an 18.5 kW electric motor, the D70-E enables regenerative braking tests, coast-down calibration, and precise power measurements under realistic conditions.
