I just got the Shoei Neotech 2 last week, I installed the Sena SRL system that was designed for this helmet. The helmet is much quieter than my old RF-1200 (I put over 80,000 miles on it), It is much more comfortable, and has better airflow. I already put about 1,000 miles into the Neotech 2 over the weekend, and I gotta say, I am very impressed with it, even with the chin bar down and the wind visor raised (with the tinted visor insert down) there wasn't too much noise, there was little to no buffeting even at 90 mph, and it stayed comfortable for over 6 hours of riding a day. I highly recommend this helmet.
