Hi everybody

I´m considering getting a 1996 Aprilia RS 250 and need to know
something.
Previously I owned a AF1 125.

What´s the interval between pistons and rings substitutions for the
RS-250?
I´d ride it basically on public roads and seldom at track days.
Is it a right choice? Should I go for a 600 4 strokes.

Cheers.
