Works
Awesome. Works well! Easy to use and holds up great. I was a perfect fit and exactly what I needed. It is pretty thick so I’m confident it will hold up great.

Perfect fit for Tao Tao DB17 front tire. Double the durability of the original inner tube.
I actually had a problem with the first one I ordered. It somehow had pin-sized holes in the same exact area of the old tube I was replacing because it was losing air. I checked the tube prior to installation, and it seemed fine. I checked the tire and there was nothing sharp inside the tire. Anyway, ordered another because it seems like a quality inner tube. Been using for a few days and it holds air perfectly. For the price, it is the best quality inner tube I've found.

Just as described
This came fast actually the very next morning and it is exactly as described and fit perfect. Seems to be very good quality also! I think it was a great value for the money and saved me going trying to find one at a store.

Thinner and lower quality than expected
Bought this for a vintage dirtbike. Upon install the tube ripped. I was surprised for the price that the tube was not thicker which would have made ripping harder. The tire levers provided are pretty small and worthless for a motorcycle rimEDIT: the team reached out and was able to address my concerns. Bumping up my review for great customer service

This fit my tire perfectly and got me back riding on the trails in no time. Seems like good quality, might buy a couple more just to have on hand

It’s terrible
The tube ripped around the valve stem I haven’t even had it in the tire and aired up for a day and come out today to the tire flat and air leaking around the valve stem it isn’t the valve stem itself it’s leaking around it indicating it ripped.

No good
Yamaha dealer told me this failed when the added air, maybe I got flawed one, but if you wanna save the hassle just buy OEM or a good brand
