Mine sounds like a big sewing machine at idle too, but sounds really nice after a few thousand rpm. I wear earplugs too, and I mainly get the low tones when I'm riding, and it's extremely pleasant, deep sounding, with earplugs in. Love trolling through small towns passing through on my various trips, and the note is almost cruiser like in my helmet, and the bike is torquey down low so, very nice.
But at idle or near it, sewing machine. From the audio clips I've heard so far on Youtube, the Muzzy gives the bike real character at idle.
Will be a significant weight loss as well because
A) losing the stock dual exhausts for a carbon fiber 2 into 1.
B) centerstand will have to come off. And they are heavy. Will miss it though, I park the bike on the centerstand every night and it makes oil change/chain maintenance very practical. Take weight off the tires, suspension. Will have to buy front and rear external stands to replace it.
On camping trips the centerstand also kicks butt when you have to park on soft earth. Kickstand is no good there.
And I can finally use the helmet lock.
But yeah, this is for light sport riding, sport touring, and commuting. It's why I chose this particular type of bike and not a 600 supersport with clip ons.
(Seriously considering a ZX-10R though, as a weekend bike to complement this, in a few years, something with a full on warp drive engine).
