Wikipedia entries are written by anybody willing to do so, qualified or not.

PS. The vibrations aren't that bad, so you can throw out the need for the balance shafts, too.

The author stated that the single-plane crankshaft doesn't need counterweights so it's lighter and spins up faster, but he also says that it needs counter-balance shafts which tend to be heavy by design and their inertia will slow down the rate of speed change.
Contradicted himself.
