4wd – BPA-4R S

The S series comes standard with knurled rollers which provides the highest traction between rollers and tires, a guarantee of an extremely high accuracy in measurement. Especially designed for standard car workshops, test lanes; this series has lower performances than our HP (High Performance) Series, maintaining the same accuracy
and balanced top level components.
Axles synchronization: Electronic linked and synchronized axles via software, made by fast and precise high frequency control of eddy current brakes to synchronize the axles in a 4wd car (Bapro’s patented system).
This to avoid differentials damage and to be more accurate in tests because power wasted in slippage inside the differentials is avoided too. Thanks also to this, BPA-4R S dyno is extremely easy to be installed and the maintenance is almost absent.
