I just purchased a Shoei Neotec II Splicer tc6. Love it so far, only have 60 miles riding time in it. My previous helmet was a Shoei RF1200. I always complained of a harmonic hum, and a long time ago posted about it here. The new Shoei does the same thing, slightly less, but it’s still there. Last time posting, no one else had this issue. Now, I wonder if it’s me, or what!? I’ll deal with it. Seems like there’s no other option with this bike exhaust.
FYI, I purchased it from Chrome Burner in the Netherlands for $628. It’s $799 everywhere. I do a ton of You Tube viewing, and saw a reviewer that recommended them. I don’t care if it’s a leftover or not, it’s brand new and is the same as any other. it comes with Sena adaptability, but I installed a Cardo Packtalk Black with no real issue. Also, I thought this was huge...I ordered last Sunday night and rec’d it Wednesday, normal ground free shipping. Thought that was amazing.
