Sena 20S Universal Helmet Clamp Kit 4.9 5 10 10
Expensive for an extra helmet convenience I bought this for an extra helmet that I have. This way I can move the 20S from helmet to helmet without having to install all the wiring. I had this same setup when I was running the SMH 5 and 10...but they're a lot cheaper than the 20S setups. I understand this is probably due to the clamp of the 20S houses more electronics, etc. I just think 70 bucks is pretty step. January 19, 2016
Great product to setup second helmet This helmet clamp kit allows you to have a second helmet all ready to go, just snap the Sena 20 on and go. November 23, 2015
Great for that second helmet This Sena 20S clamp kit makes it easy to swap the Sena 20S between two helmets. Comes with all you need for any helmet install. September 30, 2015
Perfect for additional summer helmet I needed another clamp kit for my second helmet which I wear In the summer and it's perfect. This way I didn't have to buy an additional unit. Saved a lot of money buying the additional clamp kit. September 7, 2015
My youtube unboxing review watch my Youtube unboxing video, and HJC helmet installation here is the link. https://youtu.be/6QqMXVJUnxE September 4, 2015
I love this Sena Product I have the 20S Setup and this is for my second helmet I of course own more than One motorcycle and more than One Helmet. I own a Bell Star and Shoei Hornet for my street helmets. When I ride my Triumph Scrambler, or Triumph Tiger, I feel the urge to wear the Shoei Hornet, but On my Triumph Trophy or other street bikes I like my Bell with the "Transition Lens Face shield". (It also helps that the liner is silky soft, LOL). So I needed two helmet mounts, because I am WAY to lazy to keep swapping out Sena Mounts between helmets. Revzilla is ALWAYS a great company to do business with. Delivered as promised, and a very competitive price, if not the lowest on the internet. I had a problem with a delivery item once, and NO QUESTIONS were asked from Revizilla, they just came Through with the product. I LOVE THESE GUYS! August 20, 2015
Added expandability of my 20S Bang for the buck is the only real perceived drawback for me. The 20S twin pack for use in our Arai full helmets work very well, but we both got helmets for summer use and installed two more mounting kits. All these purchases before the riding season was like a Spring cleaning of my of my wallet. That being said, I really like the sound, super easy to install in my Bell Custom 500. No removable interior on the Bell so clamp on the standard module with the boom that attaches to the clamp. Stick the speakers on the interior of the ear pockets with some included velcro. Route the wire from one side under the liner. Done. I wear a balaclava/liner every time to absorb sweat so I never feel the speakers against my ears and have never caught anything on the slightly visible wire. Not so easy in my wife's Schuberth C3. Removable interior means taking more time to route wires. Also saw another reviewer mounted the loose boom inside on a modular helmet. I followed suit and added a stick-on electrical tie down that I trimmed until the boom snapped inside, holding it in two places. So far with limited usage, my wife is able to get the helmet on and off, and raise and lower the modular front without catching the boom. Ease of use: my wife has a tough time with the force required to snap on and pop off the bluetooth module. I just do it for her and it seems very secure. Hopefully the small hook holding the module in place remains functional. June 8, 2015
Complicated at first. Complicated at first, works fine all the time. Learning curve is somewhat long, but with this many functions, it's worth it. April 20, 2015
