Just a heads up for anyone looking into a 20L tank from KTM for the '12/13 model EXC. The tank itself is available and looks just like the Acerbis 5.3 gallon, actually it says powerparts on the tank (but arrived in an Acerbis logo bag). However, there are 3 parts which are needed to install it, all 3 have not been released by KTM as of yet, and are not in the instructions on mounting it that I recieved. We only found this out after getting a hold of them to confirm we needed more parts. They are currently on back order until early December. If I had to do again..go with the Acerbis tank. Inmates confirmed its plug and play.
