QR Code Link to This Post Sena 20S, great condition, works perfectly, battery lasts all day. Upgraded to the latest firmware. Includes original box, accessories, clamp kit, adhesive mount, hardwire cable for connecting directly to a device, and cigarette-plug charging cable. If your helmet doesn't have speaker pockets you'll need velcro, or the "speaker rounds" kit from Cycle Gear ($5) Selling because I bought a system to match my buddies'. If you ride solo or your group rides Sena, this is a fair price on a complete kit, you're saving $100 over buying new, and you're not waiting on shipping from eBay. Let's block ads! (Why?)
