Took a hard head plant yesterday and decided it's time to sawzall my thor helmet and get a new one. For starters, the Thor SVR fit very well. Just for chit's and grins, I tried the Shoei something or other - fit/felt like crap - yes, even the right size, Tried the Arai top of the line and same thing; right size fit/felt like crap. Tried a mid $100 HJC and it was fine. Other than some niceties the others offered, the HJC @ a fraction of the price fit/felt perfect. Just thought I'd share my research.
