I've had the ODI lock-on grips & loved'em

.... but back in Aug 09 I put a dual gasser twist throttle on my Grizz & even thou I did an extensive search, couldn't fins any lock-ons for a twist throotle, so had to go to something else .... BUT .... a friend sent me a link showing some ODI lock-ons FOR twist throttle bikes, so I may be gett'in some of those soon to try out
