Vista Cruise Throttle Lock Install Question.

I want to install a throttle lock on my new to me VFR. What is the handlebar diameter for the 6th gens? 7/8" or 1"? I thought it was 7/8" but the throttle lock seems to be sticking at that size....

It's possible it's simply rubbing at the handlebar grip, but it just seems like the 7/8" throttle lock is too small. Are these actually 1"?

7/8 but I have also had to do some adjusting on mine to get to work smooth. You have to use the adjustment to get it to hold just enough but not too tight to bind. I have also had the need to grind off a tab for my 4th gen to clear the tank.

I put one on just a week ago and have been impressed.....particularily for $24ish dollars. It is a 7/8" diameter (I have Helibars and they are the same diameter). You have to do the following (at least I did). Firstly, you'll need a dremel and I used the tapered sand/grinding bit, a small, fine file, possibly a sharp utility knife.

1. Roll back the grip to allow access to the area where the Vista will sit.
2. Dremel off the white shouldered part of the throttle near the starter/kill switch box (a small file will help smooth this out if you are not good with a dremel). This shoulder sits up about 1/16" to maybe 1/8"....can't miss it. I have a '07 Gen 6th....so I assume all Gen 6's have this.
3. The two pronged tab on the Vista fits between the two throttle cables. Mine did not fit (and I assume yours won't). Carefully trim this down to fit - I left it a tight fit as this 'tab' is what prevents the Vista from twisting on the bar (this tab and the tension screw).
4. Once this tab is trimmed down, the Vista should fit flush against the right side of the starter/kill switch box housing.
5. The clear, thin donut fits around the bar - between the Vista and grip.....roll back your grip into position.
6. Adjust the tension screw to your liking.

Mine seems to work fine and I did a (very windy, ugh) 225 mile ride Sunday and had it 'on' a few times....worked like a charm.

On another note....I found the thumb 'button' to be way to large to easily engage the start button.....and, if needed, my four way flashers. I trimmed it way down using a sharpie (guided by tracing around a nickle I had in my pocket) to make nice, even curves. I had the Vista on/off probably 5 times, timming a little at a time, till my thumb found little or no interference reaching for the starter......did this with the dremel and smoothed over with the file. Piece of cake and it (in my opinion), looks much cleaner as it's way 'smaller' than stock, but still has the same overall shape.

I've been looking for the original on-line instructions I used for my install but can't find them. 7/8th is the right size, but you have to do a little "fine tuning." You'll have to either fill off the ridge on the inside of the grip (as per instructions I had) or slightly thin the VC lock so it fits inside the ridge (as I've read recently trying to find the original instructions).

I filled off the ridge and have a little play because I didn't screw the lock down - nothing bad for the small amount of time that it is (and should be) used. Thinning the VC lock might provide the right pressure to hold the lock against the cables properly without screwing it down. Or screw it into the switch box and not worry about some play.

I found that the spring that release the cruise is strong but too short and doesn't hold the cruise open far enough. I could never get it to hold right. If the throttle was free, than the cruise won't hold and if I got the cruise the hold the throttle won't come back in a safe manner. I took the spring to the local hardware store and found one the same size only a little weaker and about 50% longer (you can get one longer than cut to size). Now I can adjust it to snap back yet hold so hard that it's almost difficult to turn it back by hand. I also have the grip butted up against the rim on the inside end of the throttle. Normally, the grip goes over that rim but I found having it right up against instead gives just enough room for the cruise. But the spring was the big deal by far, tons better!

Good luck
