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

Replaced front tube in my 1990 DR250S with 90/90-21 front tire. Excellent quality.

The Pivotrax brand keeps coming out with better and better products. Ive used quite a few of their products and to be honest I am quite impressed, they hold up well to major abuse, very resistant to rock punctures. The perfect extra item for the just incase instances helps as well.

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

Nice thick rubber. Didn’t have a problem with it binding or twisting.

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.

Would buy again.

These tubes are the best dirtbike tubes on Amazon! They hold up well and are made of quality, lasting material.

Used it front wheel 2002 FXST. LOOKS OF GOOD QUALITY

It is as described I had no problems and the price was a great price for this tube.
