The most well-known (and easily the hardest working) expert on the Rotax 900 series sport and certified engines, Eric took a few minutes to help us profile each of the amazingly compact, powerful and fuel-efficient 900 series engines starting with our personal favorite... the 115 HP Turbocharged Rotax 914.
