Decent Starter Helmet
05 Oct 2026 by Ethan
For the price, decent choice for someone just starting out. Looks sleek and feels comfortable. It does the job well for everyday rides, and the design is simple without looking cheap. Overall, good value for money and a solid option for beginners.

Good budget helmet

Pros: Decent entry level helmet.
Cons: It's simply not as comfy as the model it replaces (the Exo 390). The 390 had more cosy inteior lining. Also, the 391 has an issue where the chin strap is closer to your throat, which is not that comfortable. Sounds a bit louder too, given that it has a vent on the top.
All in all, a really decent helmet for the price, shame they made the lining less soft. At the price, its a bargain.

Bought as my first helmet, fits really well. be sure to try on scorpion helmet before buying to make sure it fits correctly. easy to change visor to different colour. is quite bland though as a helmet but can’t complain for the price

Lovely comfortable helmet, my only flaw would be how flimsy the vent sliders can be. I have had the top vent fall off several times and have had to get it replaced.

Comfortable, removable pads, really great to know I could try it on and return if it didn't fit. Easy to open the visor with gloves on, doesn't seem to steam up much.

The only thing I would change on this lid is double D chin strap rather than quick strap
