A comment of the Nolan 103: I recently searched the market for a new flip face to replace my old NoLan 100. After trying all of the flip faces, I ended up back at the new NoLan 103. In this test, they complained the Nolan 103 visor did not ratchet up and down properely but they must have tested an early Nolan 103 because my visor ratchets up and down nicely.
I picked the 103 because (1.) I Like highly visible, yellow gear (2.) Going back to a D rng fastener after the slide lock/quick off NoLan fastener is just too clumsly (3) The 103 fit and easy of operation is far superior to my old NoLan and as good as any other helmet I looked at (4) solid metal to metal locking components.
Helmets are highly personalized and the 103 may not be for everyone. It is middle of the price range of flip faces but if you shop on the net and bargain, you can come WAY down from the list price. The 103 is quieter and much more convenient than my first one. Now I'm saving my pennies for the N-COM communication gear that fits it.
