There will be a wear ridge at the top of the bore,if a full ring was fitted it would probably break when it hit the ridge hence the step so it stops just short :y

Its a bit of a low cost work around in reality, if a bore is really stepped then it wants reboring, they realy should be honed anyway which would remove any light step.

Do all rings come with these steps , my thinking is if there was no step in the first place a build up would not occur :-\

No, standard rings are not stepped.
What can happen is that you get bore wear where the ring runs and hence the top of the bore has a setep. Fit new rings and they can smash into the step and crack the rings.
Most modern engines dont suffer such wear and hence a light hone means all i good again.
If you want to see how bad it can be, take a Ford pushrod lump apart from a Ka or older Fiesta.

I've never ventured inside a Ka engine, but I belive they're basically a Kent engine (of the MKI/II Escort etc era :-\)
