Please note, by purchasing the Rizoma License plate support, you may not need to buy the Rizoma rear turn signal mounting kit too. In most cases, the License plate support kit includes the rear turn signal adapters. Therefore, it’s always recommended to check the Rizoma License plate support technical info to verify the kit contains the brackets for Rizoma rear turn signals.
