I just got an MT03 in May. Standard exhaust, no Power Commander etc.
It's MUCH more civilised than styling suggests, being hyped to new bikers, (apparently it just gets under the 44HP limit for just-passed-test...then the kidz put race cans/Power Commanders on!). I'm really enjoying it as an old-fashioned gentlemanly ride, but with smashing agility and good brakes. Maybe I got a good one: no carburation probs at all.
BUT....
rock-hard seat, sore after 30 miles. Have spent big bucks on an Airhawk seat, otherwise would have sold it.
Try (a long ride) before you buy.
