The problem with Asian-style motorbikes in the US is their utter and total lack of power, which becomes the only thing keeping you whole on a US highway. Cars will out-brake you, cars can out-handle you. Even the MSF will counsel you that the best way out of a problem is to accelerate through it. Acceleration shifts the center of gravity back over the rear tire and improves handling. Acceleration allows you to put distance between you and the altercation you're fleeing. Acceleration gives you a direction to go that cars can't - and a 125cc Bajaj can't accelerate. There's a place for low-displacement, low-impact 2-wheeled transport. It makes perfect sense for surface streets. Things get hairy over 40mph, though. I've got a steady gig 45 miles away up a 12-lane blacktop. Could I get there on a 250? Yeah... but I could cross the Alps in an Ultralight, too. Doesn't mean it's the best craft for the job.
