The product is good just too small for me.
I didn't like it. I couldn't put my 20 oz tumbler in it. If you only drink water bottles or soda bottles it fine. But I prefer a tumbler with the straw so when I stop at a light I can drink and quickly place it back. But it's really small. Didn't fit even the skinny tumbler. Plus no matter what angle it hit the handle bars while turning.

To high, doest fit any 20oz cup.
Blocks your oil access cover door, doesnt accept most 18-20oz cup. If you do find a cup or buy theirs its to high and hits the handle bars. Had to cut slant and re-weld mine

CUP HOLDER
LOOK NICE, EASY TO INSTALL, I ALSO PURCHASE THE CUP LOOK NICE STAINLESS STEEL LOOK

Reconsider if you can
This thing is should have been better designed and is WAY overpriced for what you get. I had to order two of th for me and my wife's bykes. So imagine my dismay over the wasted $100. The only thing nice about this particular cupholder is it's location. Nevermind, I take that back. With this cupholder installed on my byke I can no longer wrap my legs around it to keep warm on cold days. Also, for those of you that'll get it anyways: Be sure that you order the overpriced $20 cup that comes with it because you can't fit any other cups in it. You can fit a water bottle and that's about it.

Works great
easy install, and works great
