My age, I guess, is catching up with me. Riding my 2005 into work today, 19 miles out, my right wrist and hand is completely numb. Letting off for just a couple of seconds revives the feelings, but decided every today that I won't be able to ride anymore until I find some kind of throttle lock... My BMW has a friction knob that allows the throttle to hold. Any ideas where I could get a throttle lock of some type?
