Companies like Baofeng and Rugged Radios both make amazing communication kits that can be used in the Kawasaki Teryx, the Teryx4, and the Teryx KRX. Many Teryx riders that are also licensed Ham radio operators swear by 2-meter frequencies. However, if you transmit in this band without a license, you may get arrested if caught. So for the casual communication radio user, you'll get the best range with a high power CB setup over some $10 walkie talkie from Amazon that has a range of less than 100 feet in the woods. Alternatively, Kenwood radios are also a great option, as are the Midland MXT MicroMobile radios. Whatever situation you find yourself in, be it an off-road emergency deep in the woods or an argument about which fishing hole you should stop at, you can have every discussion with any number of interlocutors by using the Kawasaki Teryx communication systems available at Everything Kawasaki Offroad!
