I heard on a racing show once that some professional bikers train on micro bikes; the tiny motorcycle terrors that kill fewer people every year than
you would expect.
The theory is that the low unforgiving and near instantaneous responses required to keep from killing yourself on a micro bike makes handling a larger motorcycle at high speeds much easier. Some have even said 'slugish'

I've gotten comfortable with the abike, and my initial hyper sensitivity after riding it has diminished. After the first few times riding it, driving felt like riding a couch.

Do any of you 'big' bikers who have real bikes find that after being on the abike for a while, you react or over react on larger bikes?
