Can it be translated into descriptive language that will give one a sense of how it affects drive-ability?
1) Entrance ramp to highway 0-60 mph.
2) In town 0-45 from a stoplight.
3) Highway 45-65 mph.
To try answering your questions...
1) I've never stopped on a freeway on-ramp to test the 0-60 mph speed...but I've never had a problem merging either.
2) You won't beat any motorcycle in a drag race, if that's what you're concerned about. However, you won't find a problem out pacing the normal speed of anyone leaving a stop light.
3) Never had a problem. What's your expectation though?
You'll find some slippage of the clutch from 0-15 mph. That's because of the design of all centrifugal clutches. Think of it this way... Your bike weighs 470 lbs without fuel. Add an average 200 lbs of rider and gear. Add another 10-15 lbs of stuff you're carrying around, like a laptop backpack, etc. Now you're up to close to 700 lbs. The initial slippage is while the clutch pads are trying to grab onto the clutch bell, just as if you had a manual transmission and were slipping the clutch to get a smooth takeoff from a stop. If it is that much of a concern to you, buy a Dr. Pulley HiT clutch. It has a unique design that locks the clutch pads into place with a cam. It's also very pricey.
Most of us never worry about acceleration times. I find that even when I'm accelerating at a "easy" pace, I'm still leaving everyone behind at the stop light. It's not my intention...just what happens. And once you're rolling, there is no clutch slippage, so you twist the throttle and the bike responds. Will it put you off the bike? No. It might dump a passenger if they weren't holding on though. The CVT also varies the "gearing" so smoothly that unless you are looking at the tach, you'd have no idea what rpm you were doing. It'll also surprise you because with no jerk from a gear change, you find yourself going much faster than you expected. Enough faster, that you can easily get to the point of having your bike towed away from a traffic stop.
As one person so eloquently put it, "It'll get up to killing speed. What you do with it once you're there is up to you."
