Once installed, it works great. But, there are two problems.
The "hole" that clamps over our throttle sleeve has to be inlarged a bit. I used a small sanding drum and did it a bit at a time. Pretty easy.
The other problem is sliding back the grip. It is too tight without moving the grip back. If you have heated grips, I doubt that you can move it without damaging the grip.
The nice thing is that "U" shaped part that locks into our throttle housing fits perfectly! No gerry-rigging necessary.
So, widen the hole, move the grip back and it works. I really like the easy on/off. Good luck!
