Painman I fully agree. The Madco Cam-Lock Sport was worth every penny. The parts were first class. I took off the grip and slid on the Madco and reinstalled the grip. Madco even sends grip glue. Bill at Madco even put the part in the mail on my honor that the check was going in the mail. Bill is a first class guy and his product is first class too. And I did not have to drill anything!
Beautiful!
If you are looking for an alternative, the Breakaway Throttle Lock is a piece of engineering art as well as highly functional. I've had one on a Kawa cruiser as well as my FJR and swear by it. Again, a little pricey but it last forever and is extremely adjustable.
