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

Just as described

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

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

It was good for about a month on my kx125. Out of nowhere it rips open while I’m riding. Should’ve bought Kenda the first time

Seems to be a very good tube for the price. It is 3mm thick vs standard 1.6mm

Heavy duty tube for off road bike. Works great!

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

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.

Im rolling again so far so good only time will tell its holding up 4 now

Bought these for spare and to bring them along for ‘ just in case’ hopefully I never have to use them, received these inner tube very quickly and seem very sturdy,
