The Throttlemate was on mine when I got it, but without the lever. Took me a while to figure what the heck it was. It works well enough , but I wouldn't use it other than on the freeway with low traffic.
THE INVENTOR & OWNER LIVES DOWN THE ROAD IN BELLINGHAM MASS. HE PERSONALLY INSTALLED IT ON MY BIKE AND ALL I CAN SAY IS I LOVE IT. WORKS LIKE A CHARM AND VERY TASTEFUL.
Yup. Love my Cruise-mate. Possibly the single best accessory I've put on the Road King.
I have my throttle lock tightened just enough to stay in the position if I take my hand off / but yet loose enough for me to twist the throttle back and forth.
