Ducati Panigale 959 Ducati’s 899 Panigale looks likely to be on its way out, and is expected to be replaced for 2016 by a new 959 Panigale, according to an executive order released by the California Air Resources Board (CARB), a body that certifies all motoring vehicles for sale in the U.S.A.

The new 959 Panigale is assuredly be one of the nine new variants that Ducati has recently assured the media to premiere at the upcoming EICMA Show in November alongside the just-revealed Hypermotard 939 bike.

According to the CARB document, the 959 Panigale is powered by a 955cc engine, a 57cc boost from the 899. The certification document does not reveal any further details but it is safe to assume the new bike’s engine will be a 90-degree V-Twin like other Ducati sportbikes.

What’s left unknown is how much the bore and stroke will differ from the outgoing 899 Panigale’s 100mm x 57.2mm version. An overbore to 103.1mm would bring the current motor to 955cc, or the bigger displacement could be a combo of bore and stroke increases.

Even with the larger engine, the 959 Panigale has lower hydrocarbon and carbon monoxide emission levels than the 899, seen as an attempt to meet the new Euro 4 emission standards, which will come into effect in Europe from 1 January 2016. Further details on the 959 Panigale will be revealed during the EICMA show.

It’ll be interesting to see at the EICMA show if the Ducati 959 Panigale really is an all-new variant, or if the displacement increase over the 899 Panigale comes about because of the strict Euro 4 emissions compliance for 2016, and the added engine chamber is there to help keep performance numbers in line with expectations.

In addition to the 959 Panigale, Ducati is also set to update its Hypermotard line, as according to extra documents filed with the CARB. The filing shows three new Hypers: the base model Hypermotard, the up-specs Hypermotard SP and the touring-oriented Hyperstrada.

However, the CARB filings did not reveal too much about the new motorcycles, other than the lower emissions to compliance with Euro 4. Accordingly, all three variants will use a 937cc (up from existing 821cc) engine and a six-speed gearbox. It will be interesting to see what performance gains available on the Hypermotard and baby Panigale, with respective engine displacement boosts.
