My figures are coming from weight WITH and WITHOUT mufflers.
Are you arguing that 4C's are heavier? They are.
ABC liners are in FACT heavier than steel....pick one up...measure it some time...come back to me on that.

A typical equivalent powered 4 stroke is lighter than the equivalent powered 2 Stroke with mufflers, but there are many exceptions.
A brass liner is thicker and heaver than a steel liner. Especially in older engines. However the weight penality is not very significant.
