Makes sense to me. Look how many car manufacturers put the same engine in multiple vehicles.
No official word from Honda yet, but the engine definitely has the power to be put into bikes like Deauville or the CBF.This means that a bike manufacturer spends a certain amount of money on engineering, and delivers a new engine on the market to be used in a number of different bike models. Some variations are also engineered and tested alongside the new engine, such as new mappings, new transmissions and the likes.
