I pieced it together from two parts quads I bought. The motor is from an 87, the frame is an 88. The swinger is 87, shock is 87, has rad mfg. Axle carrier, and all new bearings everywhere. Runs/rides awesome. I love it. It's my daily rider, I'm slowly building a motocross/xc quadracer to race. Gonna do a Honda front clip on the 87 frame I got. Just waiting on money
