I also don't seem to use Warbikes very well.  I tend to take them with one buggy for dropping Blast Markers, but they tend to not do much.  I should probably try to keep them on the extreme flank perhaps?  They really only seem to do well against softer support targets.
In general, I'd say a 200 point formation isn't going to do a lot to a main line unit, so a basic koS will usually best be used on the flank.
In addition to the obvious CC use, with AP5/AT5, Warbikes can actually do some damage shooting.  That makes them decent for double/shoot/support combos, even though their FF weak.  That will give you a BM and maybe one hit from the shooting for assault prep, then another hit during the actual assault.  It's not huge, but pretty good for a 200 point formation.
Also, if you have an initiative advantage and a target where direct assault is not to the Warbikes' advantage, an end-of-turn/beginning-of-turn combo is an option.  Double/shoot at the end of one turn, then Sustain Fire at the beginning of the next.  You'll average 5.3 hits on troops in the open, 3 on troops in cover.  It's not often that it's useful, but it exists as an option.
