Good product, expensive S&H

My son put this tire tube on his bike and it has done well for the last month. The only reason I didn’t give it a five star rating was because of the expensive shipping and handling

Superb Customer Service

I ordered the wrong size tube- my fault plain and simple. Called the customer service number and they were amazing. They had the new tubes shipped that day and took the wrong tubes back. The STI tube seems to work great- much thicker than the tube that was flat- and holds air fine. I'd recommend Motosport and will use them again. Thanks for the great help.

STI Heavy Duty Tube Not durable

I bought this and used it in a new back tire for my son's dirt bike. It held air for a day. keeps leaking down. Took it off found a pin hole near the stem, patched it and it held air for a day or so. Still leaked. Not sure if it's a defective tube?? Needless to say I guess I'll have to buy another one to find out. Which sucks...

A: The tube that will fit your quad, will show the same size of the tire. You will need to be under the ATV header to find them.

A: The stock tire sizes on the 2004 Yamaha TTR125L are 70/100-19 in front, and 90/100-16 at the rear. The STI Heavy Duty Tubes are available in these same exact sizes.

A: As far as I can tell, there's no 3.00x12 available for this tube. You could try a 2.50x12 and run a little higher pressure, but there's a good chance that'll shorten the tube's life. I'd suggest checking other tubes to see if they fit.
