HJC FG-17 Lorenzo Mamba Helmet 4.5 5 162 162
Excellent budget helmet Great budget helmet, feels sturdy, comfortable, and affordable. October 5, 2015
Great helmet Thanks for walking me through with this helmet! It's working great September 28, 2015
This helmet is a great deal This helmet has almost everything that I was looking for. I was going for safety and expecting to spend a lot of money, and then I found the HJC. At first the helmet was a little tight, but as I started breaking it in, the fit was almost perfect. This helmet is literally the best bang for your buck. If you want a safe helmet and your a beginner or experienced rider, this is the helmet for you. September 14, 2015
Solid helmet for the price This is my first ever helmet and I've only used it 4-5 times so far but I feel like I can give a review already. It fits me well, looks sharp, and it's DOT and Snell approved. I haven't had any issues with fogging up. Even if you exhale hard, the fog quickly fades away from the face shield. My only gripe is that the face shield really only stays in 3 positions: fully open, fully closed, and slightly cracked open. If you leave it open half way it'll fall down with the slightest force. Not really a deal breaker but still an inconvenience. Also, I don't know how it compares to other helmets but the peripheral vision seems to be a little limited. I would like it to be a little wider. Overall I am satisfied with this purchase. If nothing else, this is a very safe helmet for the price. September 11, 2015
Very comfortable and light helmet. This helmet is exactly what I need. Fits well and is light and comfortable. September 7, 2015
Nice helmet This helmet is light and offers a wide view fits very snug around cheeks (but will loosen up after a few uses) Air flow is ok, I usually ride with visor open one notch. The only problem that I have found so far is that the top of the helmet needs more padding it seems to have a pressure point after about a hour or so, but nothing major. I would buy it again September 7, 2015
Great for the Price, However Understand the demands of matte paint. So, Your looking for a full helm, we know that already. You want to go above and beyond the lousy DOT rating you want to be part of the SNELL club. Coming in at under $200 the FG-17 Packs a valuable punch, with its snell rating; Its comfortable, not overly loud, has a good locking visor, two brow vents, and a mouth vent. The DOT, and snell ratings on the back are stickers so you can opt to remove them if you don't live in a NAZl state. Almost all of the interior padding is removable for washing or even replacement, Pretty cool ehh? The visor is also removable and you can get a whole slew of different ones, I went with the smoked visor for under $20 that's a worthy investment. I opted for the Flat Black Option, what a BAD CHOICE. Trust me, If I could go back I would. One slip off your bikes seat going tumbling through a bob evens parking lot and you beautiful helmet will be scuffed for life (I never liked bob evens anyways). Even though the flat black helmet matches my Harley with "Denim Black paint" nearly perfectly, the upkeep for matte paint is more than I think most of us are willing to invest in a helmet (Not to mention the fingerprint magnet the matte paint is). I would like to see a magnet strap instead of a snap for something in the $200 price range, and after about 6 months of riding the padding is still comfortable as month 1. As to the safety of the helmet, well I haven't wrecked in it. So I can't really attest to how it holds up in a wreck. We're just going to have to trust SNELL on this one. September 2, 2015
So far so good My last hjc was a large and was a bit too big. Bought this in a med and it is a bit too small and squishes my cheeks. August 31, 2015
