2WD – BPA-2R HP

HP series is Bapro’s highest performance chassis dynamometer.
Four all connected 400 mm diameter rollers guarantee the top repeatability and accuracy. 
With a massive tubular frame made of high strength steel, this High Performance series suits all needs: Testing, R&D, Motorsport, Tuning and Chip Tuning. 
BPA-2R High Performance is suitable for any kind of power and torque levels.

All our 2wd models are upgradable to 4wd.
