PIVOTRAX-110/90-19 (4.50 X 19) or 120/90-19 Heavy Duty Motorcycle Tube - 3mm Thick - TR4

This is one of the toughest dirt bike inner tubes I’ve ever come across and for $25 you can’t beat it.

Worked perfectly on my son’s dirt bike, easy swap out. As described and fit

Seemed to be thick and heavy duty. Time will tell but so far seems like a good product. I was happy with the quality.

Been using these tubes for a few years in various bikes and haven't had any problems with them. I like the fact that they are three mil tubes, which is fairly heavy duty but they don't weigh as much as they're super heavy four mill tubes. So it saves me a little weight in the tires but still gives you decent flat protection. Definitely recommended.UPDATE 7/30/24The tube in the wheel in the photo eventually dry rotted and blew apart at the track. I did get a lot of time on it though and there was a good deal of sand in the tire when I changed it. I ordered a new replacement, and it seems the valve stem on the replacement is faulty, it won't let air out after pumped up, and I can't get a pressure reading with my pressure gauge.

I like this product

you will need a lot of lubricant to install

Exactly what i ordered

just as i expected. thick air tube fitting into a THICC tread is not an easy task. but as im sitting at mcdonalds writing this review. i can confirm that tire levelers to remove and install the wheel is worth it.
