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

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

worked as it should

Really bad my tube was not good the box was all f up. Not good dont buy here an my tube was pop.

As good as any tube you can buy. Course rubber dry rots but these are fresh... I want all the protec i can get from hitting the asphalt in point 1 seconds.

Exactly what I needed no lies in between I ask for innertube and that’s exactly what I got

If you like thick chicks youll love this 3mm inner tube. Even if youre not into thickness get this tube. Especially if you do it in the dirt. Only 4 on install cuz I have a shallow rim so it was a pain getting the valve through but it should prove worth it. Only 4 on durability cuz Ive only put a couple miles on it. Put some Shinko knobbies on an old BMW R80 ST for around the hood and going to the tavern 30 miles down a dirt/gravel road. Punctured a tubeless tire on the GS on this road so Ill see how this does. Should be fine. Front wheel & on much lighter bike. Unless catastrophic failure occurs Id recommend.

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.

I had the entire tube installed in my tire…..when i went to go put air into the tire and tube. The stem popped right off. Not very durable.

Seems to be quality product

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
