One of the things that made traveling any distance on the bike really unpleasant was the fact that I could not rest my right hand. The left I could remove from the grip and prop my elbow on the left knee. Even though I only did this for short periods at a time it made a huge difference in how my hand and wrist felt. But, the right was locked to the throttle. I had added a "cramp buster"

previously and found that it helped some but I still needed more relief than that. What I found was a throttle lock called Vista-Cruise and marketed by Sound Off Recreational, Inc.

A throttle lock is just that; what it is not is a cruise control. Yes, if you go down or up a hill the bike speeds up or slows down. And when those 18 wheel monsters go flying by, the bike will get sucked up in their draft. However, it isn't really a "lock" as such. When adjusted properly it only overcomes the return spring on the throttle. I had no problem moving the throttle on or off as needed and quite often, when passing through small one or two light towns, didn't even bother to take it off. I could run up and down through the gears with out noticing that much difference. Of course, once we got into more traffic, it was a simple matter to flick it off with my thumb.

The reward was that I got to rest my right hand. This made a huge difference and I can definitely recommend this product.

 

In order to install this device on my Thruxton three problems had to be overcome.

 Number one, you have to have room on the throttle for it. For me this was made easy as I had replaced the original grips with Gran Tourissimo grips and they were a little shorter than the originals. I also had installed bar end mirrors and had already trimmed the right grip even more.

The second problem was the fact that the throttle sleeve where the grip fit had plastic lugs on it. They dogged into the original grips to keep them from slipping on the sleeve. These were right in the way of the clamp that would pinch the throttle to hold it in place. This problem was resolved by using a Dremel tool to rough cut the lugs off and then a file to smooth the nubs so that the surface was even with the rest of the handle.

 

 

 

 

And the last problem was how to anchor the retaining clamp to the handle bar. This was accomplished by using one of the little clips provided in the kit and attaching it to the main bar clamp housing by drilling and tapping a hole and using a low profile screw.

 

 

The above clamps are the throttle cable clamps, the one with the screw is the lower.

A little care must be taken to be sure the screw doesn't extend far enough into the throttle clamp to interfere with the operation of the throttle, so a little grinding on your screw may be necessary.

 

 

And this is how the Throttle Lock anchors to the clip.

 

 

And this is how it looks when in place.

This is the bottom side of the bar.

 

 

And this is how it looks from the top..

 

 

You might notice that the thumb knob is a little high. The location of the knob is effected by where you place the screw that holds the anchor clip. If you look at the sixth picture up you will see that there is room to drill the mounting hole in several places around the throttle clamp. If you place your hole further anti-clockwise you will rotate this knob down.

Where I have the knob now makes it very convenient to flick the knob off. It is less convenient to thumb it down or on. I can do it with my right thumb but usually I do it with my left hand. In practice, this is not really a problem but if it was for you, just change the location of the screw hole. You could even drill and tap several holes giving yourself some adjustment. I'm satisfied with mine the way it is.
