Comment: The Bell Mag-helmet is a cut above the rest. It is extremely comfortable, stylish, and offers the quick release lever to change from the shaded visor. It’s the best open-face helmet on the market, as far as I’m concerned. The price was even better.

Bel Mag 9 Sena Review

Comment: Very light weight and versitle. Unfortunately the day after I purchased it I was involved in an accident when a lady pulled out in front of me. After being launched out of my seat and through my Harley equipment I was thrown accross the hood of the car and landed on the road. Needless to say there was no damage to my head, face, or neck and I owe this to this gread designed helmet. I would recommed it to anyone concerned with their safety.

Comment: Great product! Love that my Sena fits securely in a "resting" place. Comfortable fit and lightweight. Love it! Best helmet I have had to date!!

Bell Mag9 Sena Helmet Review

Comment: I purchaced the helmet and was excited about using it on an upcomming ride from NC to lexington Ky. After 100 miles, I started having a splitting headache from the helmet being to tight on my temples. My head circumference is 221/2 inches so I purchased a medium size from the reccomended sizing chart. In short the helmet is nice, but the whole trip was a painful endurance because the helmet would not break in. It was bought on line and after the 1600 mile trip, it was too used to try to get a refund.

Bell Mag 9 Sena Review

Comment: Love it. I tried an extra large and it was to small, but the 1 XL is perfect. Love the drop down sun screen and the clear shield works great. The vents are great! Keep the heat out. I am ordering another one for my wife!

Bell Mag-9 Sena Helmet Review

Comment: i like features on this helment ; bought for my sema radio,,didnt know i have to buy bracket to mount to it ,was offered on this site would not have bought if i knew the final cost




Comment: I've used this helmet several times and simply LOVE IT! It's lightweight and feels right when strapped on and riding. I even tried it with the face shiled in the up position and love the open feel and also great views with no obstructions. The drop down glasses are easy to access when riding and do a great job. I loved it so much that I purchased one for my wife.

How well does the Mag-9 Sena perform in the rain? Does water get past the main shield, either from underneath or along the gasket?
A shopper on Apr 26, 2015
Best Answer: Rode in a really hard down pour and it did come in under the shield. I do get lots of wind off of my gas tank.
