Once again, not motorcycles. I used to ride scoots, have an unlimited M/C endorsement, still, on my license.
I've been inside a whole lot of motorcycle engines, Triumph, BSA, HD, Yamaha, Honda, Kamikazie, and those seem to handle clutch disengagement pressure with no problem.
However, if you want to be changing out thrusts, take the chance of a thrust dropping out and damaging the block and crank, and eating presure plate release arms and T/O bearings, well, if you've got the time and the money, go ahead, hold it in at stop lights.
Doesn't bother me.
And if you're sitting at a stoplight, and you hear skidding tyres, don't even think about "getting out of the way", because sure as the sun rises over DC, YOU will end up faulted for the major accident as you wil have entered the intersection on a red.
Used to be on M/C, you knew where everything was, coming or going, but with the full-surround helmets, you most of the time don't have a clue for the 270 degrees or so behind your field of vision.
