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

Seemed like a decent tube put it on my enduro. 3 days later driving 45mph and notice that I smell burning rubber, pull over and the tube is completely melted. Had the psi at spec 18 psi. No reason the tube should melt and destroy my tire and rim. Find something else this product should be banned.

Great value for a thick tube. Received in 2 days. Got it installed, and have 3 rides at 10 psi with no problems. Thumbs up!

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

Great tube does the job.

I used it for my motorcycle bike. It was easy to install it looks great. Thank you

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.

Very heavy duty tube. Should hold up nicely!! One ride on it so far and no issues!!

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.

High quality tube
