AC Racing produced their subframe to offer a quality replacement part that is easy on the wallet. AC Racing realizes riding your motorcycle hard can come with consequences which resulted in making a subframe that is structurally made entirely out of 100% aluminum with 6061 billet and CNC bent mounting points and lugs. AC Racing puts every subframe through a heat treating process that results in an extremely tough product. To prevent rusting and provide durability AC Racing uses stainless steel thread inserts. The AC Racing subframe is built with tight tolerances to provide an exact OEM match and ensure an exact fit every time. AC racing uses square or round tubing to match OEM build dimensions.
