The short answer is mmmm no not reallyyyyyyy, but the long answer is:
1. You're going to be slipping the clutch more from a dig in 2nd gear, which isn't a big deal bc the clutch is wet but it will lower the longevity of it.
2. I also would never take off from 2nd because the huge lose of power. I suppose you could rev to the moon (This relates to point 1) to get that same power as taking off from 1st, but again that equates to more wear.
3. This point doesn't answer your question, but I'm adding because I watched Twist of the Wrist II last night for the first time after someone mentioned it somewhere on the forums and I can't remember who hah. **Smooth take off and shifting boils down to smooth throttle control and clutch control (among a couple other things) **
1st is the most fun gear anyway >=] Having a smooth take off is dependent on the rider!
I take off in second sometimes when I forget to drop all the way to first. You dont really have to rev the crap out of it unless youre going uphill but youre definitely slipping the clutch a lot more, and probably isnt good for the life of it.
