DMR destroyer riser reducers. The destroyer risers 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. These adapt our risers to work with 1″ bars. They are made from 6061 T-6 aluminum and available in raw aluiminum finish, black anodized, honey gold anodized, og gold anodized, and chrome. Made in U.S.A.
