For me they are a huge improvement over the stock as I can actually something out of them and they don't vibrate at all. I don't do a lot of city riding but they haven't caused me any issues lane splitting.@F3-Matt , how do you like your bar end mirrors? Can they do the job in a busy city?
Just picked up a new helmet from a guy on craigslsit who used it once before enlisting. AGV Corsa R in my exact size/color, $700 worth of lid for $300!
Always been a base-model kinda guy with helmets, so this was a nifty upgrade.
