I also use a
Vista Cruise throttle lock. The mounting hardware is easy to adapt to a variety of grips and mounting styles. It's very handy to have, even for random short term use when you need the right hand to close a helmet front or fiddle with a tank bag or farkle, etc.
I drilled right into the aluminum mount, which has a hollow underneath, then ran a stainless self tapper in to hold it. The start label is for my CRS mind, as I'm used to a left side start button, and thought it prudent not to kill any more old ladies with the Stebel air horn in Walmart's parking lot.
It's very easy to engage and disengage with a flip of the thumb, and doesn't get in the way. It's a light friction grip device, so one can easily roll the throttle off, even with the device locked. You can also easily adjust the throttle position with the device locked, if you want to roll it up or down for a grade. All the device really does is just slightly overcome the throttle cable return spring. The acorn nut adjusts tension, and as you can see, the polished metal band exerts force upon the shiny black plastic ring. I used a little piece of rubber to shore up the top set screw on the black ring. Very simple device. The only concession I've had to make is to press the starter button with my index finger knuckle, instead of with my thumb. That took a day or three to get used to, but now it seems fine. I also run a
throttle lever. The lever lends itself well to keeping two fingers on the front brake lever on Bambi roads. (I would avoid the levers that use velcro straps.)
If I were to mount another Vista Cruise, I would make one slight change near the self tapper, but it's a lengthy explanation, so I won't go into it unless requested.
