They are definitely not running all honda motors in moto3. Thats moto-2
moto-3 is any brand motor in a prototype chassis.
if it was honda motors, KTM factory team would not be racing!
its interesting that they didnt blend the 2Ts and 4Ts together for the first year like they did in motor gp is 2002 (?).
they learnt their lesson about the old 2Ts spanking the 'new' 4 strokes when placed side by side.
They say that this season or next season the 4Ts will have eclipsed the 2Ts in lap times (125 vs moto 3) (thats a quoted for KTM team manager)
However he is not taking into acount that if the 125s had any development, let alone the funding thats been put into moto3 injected into the 125 motors that they'd be going significantly faster by now.
The 2011 factory RSA125 would have most likely long since become the privateer bike and there would be a new factory machine which surpases the old one.
Aprilia R&D had lots of ideas for making more hp, but they had their funding cut
