955 is a slightly better engine.
Keep an eye out for the rear shock and linkage bearings as its a common problem.
As said very smooth motor (I had the speed triple)and does everything you would want.
I did get rid of mine though as it was almost honda like in the way it just does everything well…….but kind of soul less. 😐
I now have an Aprilia Rsvs-r which has far more soul than I can handle at the moment… 😆
