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

I ordered the heavy duty tubes for my BMW R1200GS (21 front wheel) and they fit correctly and where easy to mount. The tubes are also packed in a plastic bag inside the carton for easy and not stinky transportation if used for a spare tube.

The install was a bit rougher due to the extra thickness of the tube. Absolutely no complaints though. Thicker tubes take quite a bit more punishment.

Works

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.

Exactly what I needed no lies in between I ask for innertube and that’s exactly what I got

seems okay so far, made a difference on riding...

Only had it on my bike for a month and certainly hadn’t been riding a ton. Came out one morning and tire was completely flat. When we pulled it off found this split in the tube. NOT HAPPY

Works as intended

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.

Great heavy thick rubber inner tube for motorcycles. Fast ship.
