Hands down, one of the best riding accessories I have bought is a tinted visor for my Scorpion R-710 helmet. This thing is AMAZING and worth every penny. If mine broke today, I would immediately buy another one. It is THAT good.
I was really worried it would be too dark in many cases, but that has not been the case once in over 2,000+ miles of using it. Below you can see some comparison images!
More riding gear reviews coming soon!
