I think you can buy lock ons designed specifically for grip shift, i guess they're just shorter than standard ones. But i don't see why you couldn't use normal ones as long as you have enough space on your bars.
hi can lock on grips be used with twist grip gears , i curently have 110mm slide on grips on my bike is this the length of most lock on grips .
I use these:- http://www.canecreek.com/component-othe ... king-grips
i got them from CRC but it appears they don't do them now.
A trawl through the interweb my find a UK source.
I cut off the lugs on the inside so only use the outer lockring as cooldad suggests. Works fine.

standard is around 130mm - 135mm
most lok-on are a total of 135mm, so the grip is really 115mm or so (10mm each side for coller)
best and biggest I have seen are

they are bmx grips, so the rubber is a bit soft, and if you have gear shifters they can get in the way........

More expensive than when I got them. If you decide to get them I can let you have my spare set of lockons?
