2wd – BPA-2R 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. Equipped by eddy current brake all power is directly transferred from the wheels to the load cell.
Especially designed for standard car workshops, test lanes; this series has lower performances than our HP (High Performance) Series, keeping the same accuracy and top level components, allowing to minimize test bench maintenance, over the years. All our 2wd models are upgradable to 4wd.
