I have a 2006 Suzuki DRZ400 “S model” I want to swap the original front rotor (disc) for a SM Model 310mm front rotor (disc). I want to use my original front break caliper; I therefore need a caliper adapter plate to make this possible. Can any one tell me where I can buy this caliper adapter plate to accommodate the 310mm rotor (disc) or does any one have drawings / CAD models for it ???????
