Hi people I currently have a Shoe RF1100 which I've had since mid 2010. It's a fantastic helmet. Prior to that I owned a Kabuto Samui (or something). The Shoei is a little tired now, feeling lose on the head and being over 6 years old I think it's due for replacement. To replace the Shoei I am seriously considering a Shark Speed R 2 Carbon or Spartan Carbon. Coming from the Shoei I'm concerned that the Shark might be too loud because I ride naked bikes. Additionally the drop down tinted visor is also something I'm not sure about. When trying the helmets on in store the foam around the ears isn't quite as pillow like as the Shoei's (probably because my helmet has moulded to my head). On the Shark Vision R at least the drop down visor was actually obstructing my vision but I understand this will likely be different with the other two models. Unfortunately the Speer R 2 carbon and Spartan carbon were not in stock in my size. The things I liked were the weight and the fact that the Sharks generally seemed more compact. What got me looking at Shark as a brand in the first place was the Sharp helmet testing ratings. I don't know full details of how the tests are conducted and maybe this shouldn't be swaying me as much as fit and comfort and brand reputation. I don't know if these ratings were even a big thing back in 2010 because I bought the Shoei for fit, comfort and quality of build. Blah blah blah, the main point of my post is to ask if anyone has experience with either the Shark Speed R 2 or the Shark Spartan Carbon, particularly on naked bikes. Cheers.
