Why are Harley engines underpowered?

Cruisers, like Harley Davidson bikes, are slower than sports bikes because they have push-rod valve trains and are air-cooled, and can therefore not operate at high engine RPMs to develop lots of power.

Why are Harleys so weak?

Although the long stroke and firing angle limit rpm and thus the amount of air that can be drawn in before mechanical catastrophe looms, Harley engines produce low power because it can be offset against high torque at low rpm.

Why do Harley-Davidson’s vibrate so much?

The vibration of Harleys is mostly because of the V-Twin motors that power them. The smaller AoD allows for a more compact engine but increases the engine’s shaking forces. As a result, Harleys vibrate more than other motorcycle brands such as Ducati and Moto Guzzi, even though they use the same V-Twin engine.

Those that have issues installed the 120R out of the box. Those that have not had issues pulled the top end to check for a true bore and piston to cylinder fitment. They also checked crank runout and some even went to the trouble to pull the crank to have it welded.
