I received my Nolan N-104 from Revzilla last week and have had a few chances to wear it. Seattle has had a couple of nice days recently. the Nolan has the best vision of any helmet I have ever worn, the Shoei Qwest I tried on seemed to have pretty good visibility also, maybe as good as the Nolan. the N-104 is quiet, visor sealss tightly against rain, the sun visor seemed a bit short but I found after using it for awhile that it works very well. The modular release is a two button operation that I have yet to master with gloves on but overall I am very happy with the helmet. Cab Yellos isn't hi-viz but it does stand out.
The Nolan replaces a Gen 1 Bell Revolver which was hands down the worst helmet I have ever owned. Noisy, most of the rubber molding was held on by duct tape within a month of owning it, the rubber seal that the top of the visor supposedly seals against tore at about month three, leaked like a sieve in the rain and we get our share of it here. I bought it on sale to replace the HJC CL-16 that I gave a bad case of road rash to last in April 2012. I should have just bought another CL-16 at the time.
