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

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.

Super stoked to try out this companys tubes and tires....I heard alot of good reviews on them

Ordered it for a motorcycle my son was fixing up for his stepdaughters. Went on each and now it’s on the road. It is a really great product, durable and well priced

Seems to be a very good tube for the price. It is 3mm thick vs standard 1.6mm

Works as intended

Fit perfectly on my Hawk DLX. Great price. Nice and thick.

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

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!

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.
