[5] BUILT-IN DYNAMIC BALANCER (BALANCER MODEL ONLY)

Engine are sure to vibrate by piston's reciprocation.
Theoretically, three-cylinder engines are much less
prone to cause vibration than four-cylinder ones (second
inertia, etc.). However, any engine has many moving
parts in addition to its pistons and cannot be completely
free from vibration.
The four cylinder engine is fitted with balance weight
on crankcase to absorb the second inertia mentioned
above and reduce vibration.
