The phrase "rotating masses" refers to objects or parts that are turning or spinning around a fixed point. It commonly describes things like wheels, flywheels, or other rotating parts in machinery or systems. Full definition
That translates to improved responsiveness from a reduction in rotating mass and, for models with a third pedal, should mean reduced clutch effort. (automobilemag.com)
The lower rotating masses on the front axle also ensure a more direct steering response — which is especially effective in high - speed cornering. (greencarcongress.com)
The advantages over a conventional five - hole screwed fitting include better driving dynamics and performance thanks to fewer rotating masses and, of course, faster wheel changes. (topspeed.com)
