PIVOTRAX 90/90-21 or 80/100-21 (3.00 X 21) Heavy Duty Motorcycle Tube - 3mm Thick - TR4

Was very impressed with how thick the tube was. Ive got about a thousand miles on it now with no problems whatsoever doing a severe amount of off-road riding. I am a larger guy about 300 lb with an Enduro and its not having any trouble with weight or abuse.

Just as described

I didnt install them yet but they look really thick and high quality

The install was a bit rougher due to the extra thickness of the tube. Absolutely no complaints though. Thicker tubes take quite a bit more punishment.

Replaced front tube in my 1990 DR250S with 90/90-21 front tire. Excellent quality.

Update 4/27/23 - these people decided to hide my original review. I hate shady businesses. I got the tube in the mail fairly quickly. Got my bike broken down and the tire off, pulled the old tube out and installed the new tube out of the box. When I get the tire all put back together and on the bike, I realize the inner valve stem was bent (Straight out of the box). Made for a pain in the ass because the parts stores are a long ways from my house and on a Sunday everything is closed. It would be nice if they could send me a replacement valve stem.

Very well made..I have my buddy using them on his bike now too..so much easier too get the tire back on the wheel without pinching the tube

Great price fast shipping, seems to work just as it should

the only thing i did not like is that it was hard to blow up, im not sure if the valve is different from my old one

When I aired it up to seat the bead and then let air out I was like WTF? I did this tube swap in my living room because it was cold in the garage. Living room stank for an hour. Tube seems good but man what a stink.
