If you compare the 2 engines, they are quite similar. Same valve sizes, same small pushrods on the same single overhead cam. Same output power. Ok cams are connected to the crank with a chain from the back of the crank.
Design wise it's like the idea you have from both countrys, hot italian, or wirtschaftlich german.
I like it hot.
I once steed op a r1100s, it feels like a sofa.
