  • Overall its a great value for money helmet offering good protection and comfort which you would only expect in more expensive helmets.
  • This helmet is an outstanding value. My street helmet is an HJC so I decided to give this a try for my dual sport.
Bell MX-9 Adventure MIPS Off-Road Motorcycle Helmet
  • Great for dual sport. Really easy to remove the faceshield, which is nice for cleaning/replacing.
  • While it may not be have some of the adjustments and top level safety standards that higher end hemets have (closeable vents, quick adjustments for visor, etc), it does everything I want in a helmet.
  • Exceeding my expectations in every way, lighter and more comfortable with a lens that just wont fog!

  • The helmet fits perfectly and is very comfortable, credit goes to the fabric used in the cheek pads.

  • The fit is the same as most HJC helmets.
  • Nice helmet, fits good, a little snug on the face. Looks good and accepts intercom well.
  • Downside is ventilation. Also, I wish it was snell certified.

What customers say about "Features"
HJC DS-X1 (XF-21-510-571) Solid Helmet (Silver, X-Small)
  • The visor is adjustable o believe 10 degrees,which is a nice feature.
  • Vents are easy to use with gloves on. I do have a few small complaints beveled shield makes weird water droplet effect at certain angles, almost distorts things .
  • The helmet offers a wide viewing angle, ideal for some cross country riding.
  • The helmet has good airflow, the visor is well designed so it doesnt catch a lot of wind unless you are looking at the clouds, and it is comfortable.
  • This helmet doesn't have a ton of bells and whistles, but gets the job done!
Bell MX-9 Adventure MIPS Off-Road Motorcycle Helmet
  • Nice being able to remove the visor for more street riding so it doesn't pull your head around too much.
  • I don’t think you can go wrong with this helmet. It is lightweight, has a huge field of view, the padding and MIPS protection are stellar, and has decent ventilation.
  • It comes with a clear and tinted visor. Also of top importance, it looks amazing!
  • Peak has two adjustment points for a pefect setting, and i also got the transitions lens so day or night its perfect!
  • Helmet fits great, and is very comfortable. It’s also great at high speeds, stays very stable. But after about 6 months of owning the helmet the orange color has completely faded to almost white. Not very impressed by that.
  • The vent in front is close-able. This means it is possible for you to get wet when it rains through the top vents.
