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

Muy Bueno

Fit just like it was supposed to. Seems durable. Pinched it pretty good at install. Was worried I put a hole in it. Nope thank goodness it was as thick as it is.

I inflated mine alittle to check the tube out, one side immediately bubbled out, shouldnt it inflate consistently?

Had a flat. Tire is new. This is a good quality inner tube compared to others.

Seems to be quality product

Heavy duty tube. Ive tried different products from this company and Im completely satisfied with their stuff. Keep making quality products and Ill keep coming back!

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.

Nice tube

Good product nice and thick did not put a hole in with my spoons!

Was very impressed with how thick the tube was. Ive got about a thousand miles on it now with no problems whatsoever doing a severe amount of off-road riding. I am a larger guy about 300 lb with an Enduro and its not having any trouble with weight or abuse.
