This is the BRG Second Gen SV650 gas tank bracket that supports the back end of the gas tank. It is nothing really fancy and is the same design as stock except it's made out of aluminum. It's just over a half a pound lighter then the stock bracket. You'll use your original mounting bolts c We've been selling them for approximately a year and a half now and they've been holding up pretty well have had no complaints about them breaking. They seem to do an adequate job of holding the tank out when you're on the air box and/or throttle bodies.
