I've owned both over the years. I like the Shoei much better. It's light, fit, noise reduction, and ventilation are much better with the RF 1000. It's my current helmet of choice. I don't think they discontunued the RF 1000 though? They do cost more, like an Arai does, but it's a small investment spread over say the 5 years you would be using it. What's your melon worth and do you want to protect it with the best you can afford or save a few bucks for something else? Check an Arai for fit too. Depends on the shape of your head and face as to what manufacturer is a better fit for you.charleym3 said:
