  • Excellent for Sportbike Commuting
Color: Black(Tailbag)
I was naïve and used to ride around hunched over with a backpack. Backpacks are large and create drag, while this tail bag does quite the opposite and suits my needs and more. This is a great priced bag that is relatively sturdy and carries all my belongings. It can strap down well to my CBR even with an aftermarket seat cover. It perfectly sits on my MT07 / FZ07 rear passenger pillion. It can compact really flat to be aerodynamic an can expand big enough for my Shoei X14, size Medium. (But not enough room for much else if the helmet is inside.) The minute or two it takes to clip the bag in is worth it to save my back for longer rides, and lets me carry even more with no excuse since its all on the bike. I leave the backpack straps on to make things even quicker and I love the extra accessories to make commuting in all types of riding weather doable. The only real downside is that the straps used to hold it on to the bike get slightly loose if you are carrying heavier things making me have to readjust it every ride. Also that if you want to ride without the bag leaving the clips, the clips just dangle around and it would've been nice if they clipped into each other to make it neater. Nonetheless, it is an excellent and great priced tail bag. ... show more

  • Great bag but doesn’t hold my helmet
Color: Black(Tailbag)
Attached are some pictures. For scale, my helmet is a XL and my lunch box is one of the bigger ones you can get, an unusual size that’s bigger than most cloth lunchboxes. This advertises that a helmet can fit, but mine is a pretty common helmet (Scorpion line) and at XL it does not fit. Well, it fits but it won’t zip completely. The picture attached shows the helmet in and as far as I can zip which isn’t far at all. I’m sure a L would fit, but I can’t say for sure. On the flip side, my large lunch box does fit! Which is what I wanted this for, mostly, for those items that I want to carry with me while I’m actively riding. The helmet not fitting is not that big of a deal because I usually take my helmet with me wherever I go. Which brings me to my next point… This is not very well secured to prevent theft. You can get put a small, TSA baggage sized lock on the zippers, but all a thief needs to do is unbuckle the pack from the attached straps and walk off with the whole bag and then destroy the lock in a secure place. There is NO way to secure those straps. The straps do make it so someone can’t just up and take the bag off your bike in one go and it also does keep it secured while riding. I’ve put about 100 miles on my bike with this thing on and it hasn’t come off yet. It’s still snug in there. Max speed I’ve gone with this on is 80 MPH to further give you an idea of how well it stays attached without falling off. It is universal so likely will fit your bike. This is attached to my 2022 Kawasaki Ninja 650 and it fits well under the rear latching compartment. It does take up my backseat, so no riders will be able to sit back there while this is on. But the pack does come with backpack straps, so you could either wear the pack or strap it to your passenger. I see the waterproof cloth and it seems to be made of decent quality. It has rubber elastics all around so it should fit very snug under the bag to keep it in place in case of rain. It has made it slightly more difficult to get onto my bike as I would usually have to glide my leg over my back seat and that’s a little more difficult with this on and will be even more challenging with something like my lunchbox in it. But it’s not impossible to get on even by yourself without help. All in all, it’s great and I like it. I like that it has reflectors on it which will also help keep me more noticeable in darker environments too. They’re not extremely noticeable, but it adds to what I already had just a tad without being too much. ... show more

  • Good helmet bag, not great for luggage rack
Color: Black(Tailbag)
I love this bag, for the price. It holds a helmet with Bluetooth attachment. Or a small amount of stuff while wearing helmet. My 2 complaints are... 1. The straps to secure the bag are designed for a rear seat, not a luggage rack. Tightening the straps is difficult because they are under the bag. I use a bungee or web strap (cheap belt that came with a pair of shorts) as added security to hold it snug to rack. 2. The d rings and strap accessory attachment points are plastic. So I worry they will break. The bag itself seems durable for the price point. Zippers seem good, material is good quality for price. I've worn it as a backpack and it's fine. I prefer to mount to rack tho. I like that it gives me a safe way to store helmet at home and work. I put helmet in bag, un hook straps, take bag inside and my helmet is kept in the bag when not in use. At work this keeps people from wanting to touch my helmet. I can/have put one days clothes in bottom of bag (pants, shirt, socks, undies) and I can still fit helmet and zip bag closed. I wear a small helmet so maybe if u have a larger size u can't do this. If the durability lasts more than one summer, it's well worth the price. I'd buy this bag new every spring as long as lasts till fall. So far so good. If it lasts 2 or 3 years even better. Someone with multiple helmets may choose something like this just for helmet storage at home. I dont think a helmet with mounted camera would fit, but I can't say for sure. Maybe disconnect camera and set it inside helmet when storing. I'm not there yet with camera equipment so I'll have to figure that out later. ... show more

  • Worth the price! I bought a 2nd for back up!
Color: Black(Tailbag)
It fits the size small agv pista gp rr with room!!! I see other reviews about it not fitting g the helmet but it definitely fits one with a smaller shell like the pista. I never take the time to write reviews but this one is definitely warranted. This product is easily 5 star for the price point. It’s not like the other flimsy Amazon knock off back packs, this one feels solid and durable. I put it under a mini stress test pulling hard on the straps and joints to get it to tear and it didn’t. I didn’t give it 100% but I have it a solid 70% and I’m on the stronger end. It comes with buckles straps and a net to secure it to the seat but I will always recommend to add an additional bungee or 2 to the bag/bikeseat if you secure it to the seat because I never trust plastic buckles to begin with even though these feel really solid. I’m ordering a second one just to have on hand because this bag for this price point is great. ... show more
