Review: Best of breed steering stem mount - I've used at least 6 different motorcycle steering stem mounts that work similarly in fashion to these however this one is far superior to every other design that I've ever tried. Most of them are often difficult to mount securely into the steering stem. Some are difficult to insert initially, some move around a good amount due to rubber bushings but this one is easy to setup, remains super secure, and is easy to remove. I have mixed feelings about the security Torx bolt but it's probably isolated to my use since I am frequently installing and removing because I use these to temporarily mount cameras or test gear to different motorcycles. It's a quality product and I've purchased several over the last couple of years and recommend repeatedly. ## Features - The ball base designed to fit into the cylindrical or hexagonal bore wall of motorcycle fork stems.
