AC Racing Subframes replace that heavy O.E.M. subframe with lightweight aluminum for a racer-fast look. Exact duplicate of the stock subframe, except built from 100% aluminum. Built from square or round tubing for a perfect O.E.M. bolt-on match. Mounting points and lugs are made of CNC-bent, 6061 billet for quality and accuracy. Stainless steel, threaded inserts are used to prevent rusting and prolong thread wear. Heat treated for maximum strength.

Comments about AC Racing Motorcycle Subframes:
I just bought an AC subframe for My 09 RMZ 250 and noticed it was light and seems pretty durable. But my problem was my subframe came without a screw thread hole on the exhuast side plate. So I had to send it to AC so they can install it. The fit with the airbox was pretty tight for some reason too. If you get one, just make sure its all right and fits before you throw away your box.
