Another good indicator is that the stroke (86mm) was unchanged, and only the bore enlarged (86mm>92mm). Typically engines with larger bore/stroke ratios like revving more than ones with lower bore/stroke ratios.

Especially when that extra space is used for larger valves. Most of the time when getting a displacement bump OEMs go with a longer stroke which negatively impacts high revs. Fortunately they didn’t go that route. There’s no reason this new engine should be less rev happy.
