Physics dictates that rotational inertia impedes acceleration, which is why a lighter flywheel is considered to be a performance mod.
Less rotating mass = more acceleration, if all else is equal.
I was hoping someone had done the maths on costs and comparative effects of losing 1Kg from the flywheel, rear sprocket, and back wheel & tyre?
Weight reduction of the sprocket, wheel and tyre also has the benefit of reducing unsprung weight making the suspension’s job easier too.
