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

Heavy duty

As described, heavy duty tube. I have used several tire products of the ProTeaz line and have been pleased.

Very well made..I have my buddy using them on his bike now too..so much easier too get the tire back on the wheel without pinching the tube

This inner tube is thick, 3mm thickness to be exact. Did struggle a little on install but fit very well in tire and wheel. No problems yet but will update!

Put on Suzuki savage front was impressed with thickness made spooning tire easer due to not pinching. They also include a valve stem removal cap. I would buy again if needed.

Looks like nice quality, have not used or installed, bought as a backup, when needed. Would buy again.

Great value and so far holding up well to the abuse with lower tire pressures.

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

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.

I didnt install them yet but they look really thick and high quality
