The brand new Aprilia RS-GP prototype has made its debut in the hands of factory riders Stefan Bradl and Alvaro Bautista at the Losail circuit in Qatar. The press release is very light on detail, other than mentioning that the 2016 bike, a brand new machine designed from the ground up, was a big improvement on the 2015 machine. The lack of detail is hardly surprising, the entire test was shrouded in secrecy, with even normally well-informed sources not being able to extract any information.
From photos, the bike looks like a cross between the former Aprilia RS-GP and Honda's RC213V machine. The bike now has two separate exhaust routes, featuring separate pipes for the front and rear cylinder banks of the V4 engine. It is believed that the angle between the cylinder banks has been enlarged, though that is not immediately visible from the photos.
