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

This tire is very good. Second one I have had on my DR350. It works perfectly for adventure biking and reliable in the woods/dirt.great tire

They hold up OK. Not the greatest but for the price its good. I had recently bought one. Im almost positive it had a hole in it when it was delivered but I cant prove it because I had already installed it in the tire before I aired it up.

Fit just like it was supposed to. Seems durable. Pinched it pretty good at install. Was worried I put a hole in it. Nope thank goodness it was as thick as it is.

Great value fits great love it

Works

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.

These tubes are the best dirtbike tubes on Amazon! They hold up well and are made of quality, lasting material.

I got a flat and had to cha ge the tube it was a pain but thays not the tube fault its holding up well

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.

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.
