Most probably you can get one US pan in Europe, without having it shipped from the US as the Akra racing exhaust is available in Europe too, hehe.Came across this on VisroDown
Not sure if that means you can make due with an EU-spec 1299 belly pan, or if you need to try and get a 959 US spec pan shipped over.
(although I guess they should sell something compliant with the Racing AKra)
The 60mm diameter is the same as the 1299, but most probably you will need a remap specifically for the 959. However, will it be compliant with the Euro 4 if you adapt a 1299 aftermarket exhaust?? :S
If Ducati hasn't been able to do it...
