This thread has proved to be very entertaining. For dirt, I use the clutch to take off, then to cross the neutral gate from 1st to 2nd, then never again. Street bikes I will use it to get to the afore mentioned 2nd gear, and on downshifts. Since the middle '70's (bought my first bike in late 1975), I've never had a transmission failure due to not using the clutch. Just my experience. Some people can tear up a steel ball with a rubber hammer, so do whatever you're comfortable with..
