Mine is like the one from AMazon that Hendrcs posted, aI will say if your throttle sleeve is plastic/neoprene, it will wear the throttle lock ,but you can back it off quickly without hitting the lever, in a quick think move. I use it for warming up also, as mentioned earlier, but I like it on the freeway. I find you have to tighten the adjustment more for freeway speeds than when idling high, depending upon you return spring(s). Worth every penny, that picture is one for use with dual cables, push pull, they also have one that is a bit more bulky for single cable use .
