Yeah...it is lighter than stock, but I was so ready to put it on that I didnt really take the time to compare it with the stock closely. I got the swingarm, carrier, and a new steel braided brakeline for 750 shipped to my door. The chain adjustment is so awesome. Takes 2 min and you are done. I absolutely love it. I still need to put the brakeline on. I need to clean the backend up a little. Powdercoat the caliper and all the other parts that I had painted myself. Thats for the winter.
