Inliners International Forums General Discussion Engines Inline 6 Crank Needs Re-balance 4 lighter Pistons?

As I recall from vibrations class nearly fifty years ago, the inline 6 and 8 cylinder engines are the "best" as far being inherently balanced, as 56er points out above. According to Professor Taylor's textbook on IC engines, the 60-degree V-12 and 45-degree V-16 behave similarly. An inline four or a V-8 have an inherent out-of-balance problem.
