It refers to the replacement of, usually, bearings, rings, related and appropriate gaskets, valve guides, and other worn parts. This is in the usual cases of age without serious neglect and/or abuse. Include the case of these machines, I would change the timing chain and tensioner & guides as long as it's apart. This includes valves & seats resurfacing also. BTW: while a comp ck doesn't specifically tell you it's the valves or rings, one can usually conclude with logical accuracy if only one cylinder is low and the rest are high, it's a valve; if all are equally low, it's likely the rings. To further confirm it's rings, squirt oil in the cylinders one at a time and so the comp ck; if the readings of that comp ck are higher it is rings. Rings wear rather evenly; it's not likely that the valves will do the same but the results of the second ck will give you a fairly accurate conclusion without either the $300 for exploratory surgery or the tools required for a leakdown test.

MODERN sport bikes, ones with fairings and rev higher than 10,000 RPM. I don't really consider the 700S as a sport bike like a CBR or interceptor more of a sporty standard. But I guess back in its day it was considered one.
