This came off of a stock 1981 GS650E Suzuki. This is a pretty nice system although it does has some scraps and dings. Look at the pics for the best info. The owner removed these because every so often he could hear a rattle coming from one side. I heard it,it was very faint. It's had the noise over a year. These will clean up nicely and they have not been drilled or modified,all stock. I can send more pics if you want them.
