They are cheap pieces of plastic (that don't belong on a V-Max) but will twist off. I made some good aluminum ones when I changed grips. I use a touch of spray paint as cement to hold new grips---- be quick.:eusa_dance:

BTW:
I used a rubber stopper, a 2.5" long Allen head bolt, washer/w nut epoxied to it. All this to hold the bar end in place and be easily removable. Works great--- even sold a few pair.
