DMR Destroyer riser reducers. These fit our Destroyer risers and are machined for mx moto style bars that are 1-1/8" in the center where the risers clamp on, but these reducers/adapters reduce the clamping area down on our risers to work on bars that are 1" in the clamping area. They are made from 6061 T-6 aluminum and available in raw aluiminum finish, black anodized, honey gold anodized, og gold anodized, and chrome. These are solid with no slipping or movement. For those who are unsure of using a reducer, we have plenty of stunt guys using these with zero issues. This same design has been used in the motocross world for decades. Made in U.S.A.
