Well your part may be good but I would not know because what you sent was not what I ordered so the way I see it you need some sales help or the ones you have need training because I'm stuck with a part I did not order and can not use.
Installed the quality risers on my 2007 Vulcsn. Unfortunately they raised the bars a little too high which caused my control cables to be too tight when the bars turned to the left and right stops. I had to reroute the control cables behind the tree which, in my mind, is not optimal. I made the mistake of committing to the installation (used red loctite) before thoroughly checking the fit. My fault. In hindsight, I should have purchased risers which did not require the reroute. They are a quality product and the service was great from the Superstore.
I was 4000 miles from home making a U turn when the throttle grip just broke. After picking up the bike, I found the throttle partly functional and was able to get home. Upon removal and inspection it looked like a clean separation of the metal tubing about in the middle. The rubber portion was still intact. Clearly materials defect. The grip was the first accessory on my new 2013 Road Glide which now has 85000 miles. Unfortunately, I had not read recent reviews before replacing. Seems like a recall could be in order.
I use this holder all the time. My 40oz Hydroflask fits perfectly in this holder which is mounted on my left side saddle bag guard rail. If you want ice cold water on a 100 degree day do yourself a favor and get a Hydroflask. I fill it halfway with ice and then fill it with water. Mine has a flip up mouth piece. I can easily grab it and take swig at any time using one hand. The only time I don't use it is when my wife is riding with me because she said it hits the back of her calf. That's when I put the Hydroflask in either saddle bag or tour pak.
