Well, I just did a 120 mile ride to go work on my kid's CBRF2,(again!) and got to try my new Go-Cruise throttle lock. It is very simple, clamps over the grip and rests on the brake lever. I had to move my Grip Puppies outboard a bit to make room for it but overall I like it. You have to over rotate a bit when setting it since there is some springback from the rubber grip but once set holds the throttle well. Works as good as my old $125 Throttlemeister for $20.
I'd post a pic but I am a loser and don't have any.
