The Sportbike Cam Mount bolts to the fuel tank using your existing bolt holes. Itr ships with longer bolts to make it easy. Any tripod mount unit will bolt to it. The riser is to elevate digital cameras to get a decent view. Has Velcro on the platform to pad the camera base and secure lens covers on tethers etc. The large knob makes it easy to remove the camera and take it with you.
Drawbacks. 1. Can't get your chin down low on the tank at speed!
2. Mount interfers with use of a tank bag.
3. You need a good quality wind screen to view through without distortion.
Overall, it's well worth the price.
