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

This tube is a back up tube so I have not installed it yet. For the money, the tube looks very durable and the air value looks identical to what I have now. I would buy it again when the time comes.

I bought this tube and installed it, will honestly say its the thickest tube Ive ever attempted to run. Installed it and everything was great. Took the bike out for a rip down the dirt and felt accomplished as any person would after putting a tube in. Got back and threw the kickstand down then walked away. Started working on another bike and heard a short brief hissing noise. Went back to the bike and the tire was flat yet again. Removed and found a pin hole next to the valve stem. Had to pull a tube from a different bike and its been fine ever sence

Very good product very satisfied with it

Best tube I’ve ordered in years. Super thick rubber.

Had a flat. Tire is new. This is a good quality inner tube compared to others.

It came with holes all in it not worth it buy from somewhere else

I have not rode my bike yet but tire and tube balanced with no weights and the tube weighs quite a bit which I like. I wish they made one that fit my rear tire.

Excellent product. Easy to install A+++++

Appears to be high quality, not yet installed.

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
