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

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,

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.

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

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.

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

Used it front wheel 2002 FXST. LOOKS OF GOOD QUALITY

Just got mine put in and was absolutely impressed with these tubes chonkiness, these bad boys are beefy compared to a standard tube. Shipped quick and was not much if any more difficult than installing a standard tube. Would definitely recommend either soapy water or talcum powder to help get it in and inflate properly but honestly youd have to try to twist this beef cake of a tube while putting it in.

Would buy again.

Works as intended

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.
