Welcome. I have installed a Vista Cruise with Oxford heated grips on my 2013 650. I first ordered a spare throttle grip tube to "work" on. I then ground off the flanges molded into the tube so the Vista would fit. The Oxford grips come with Super Glue to affix the grip. What that means is, you must be very certain of where you want the grip to be positioned AND you must be very fast in the actual installation. Super Glue will "lock up" in about 1 second! You can see where I placed the cable droop and how I anchored the Vista Cruise in the following photos...I had to do a little grinding on the supplied Vista Cruise anchor tab and I used some pliers to crush the anchor plate around the tab to remove any play.
Both the throttle lock and heated grips work very well.
