SHOEI RF-1100 MOTORCYCLE HELMET
This is a beautiful helmet, well crafted, with the spoiler an uninterrupted part of the helmet's form. The visor seals strongly to its gasket by means of a system Shoei calls "Q.R.S.A." - Quick Release Self Adjusting base plate system. It actually pulls the visor back into the helmet, seating it against the seal. It works.
First Impressions:
* Feels lighter on my head than my Arai Vector.
* Better peripheral view than the Arai or my last RF-1000.
* Air flows well through the helmet, drawn by newly placed low pressure outlets. Shoei says that there's better negative pressure higher up on the helmet's rear section than below the spoiler as previously designed.
* Anti-fogging chin/shield vents seem to work well but I haven't had a chance to test it in the rain yet.
* Quiet and stable at high speed. This is where the RF series helmets really shine.
* Snell 2010 rating. After reading Motorcyclist magazine's controversial "Blowin' The Lid Off" article and hearing of the new Snell testing protocols I decided I'd put off buying a new lid until October, '09 when the Snell 2010 helmets would begin to become available. The RF-1100 is one of them.
* 5 shell sizes. 3 shell sizes are good. 5 is great!
I paid US$319.00 for my RF-1100 but I see now that it's been changed to $359.00. I must have unwittingly taken advantage of an error- perhaps the price was left over from the old RF-1000 solid. Anyway, that $319 included shipping and tax, since there was none of either.
Even though the price has been corrected I can recommend
http://www.thehelmetcenter.com/ as a good source. They responded immediately when I had questions and were very friendly. I ordered on a Monday and had the helmet Wednesday morning.
If you live near Phoenix, Arizona you can save a few dollars by buying at the store itself.
