STI Tire & Wheel, acclaimed for groundbreaking ATV / UTV products such as Black Diamond tires and HD Alloy Series wheels, has brought its innovative thinking further into the off-road motorcycle market with the expansion of its recently-introduced motorcycle inner tube line. How could a fundamental item such as a dirt bike inner tube possibly be made different or better? Glad you asked.

  • Each uses a 4 mm spec, making it 60 percent beefier than most heavy duty tubes.
  • Specifically designed for the ultimate in severe applications and has already been proven in off-road competition.
  • Priced considerably less than comparable rivals.

STI Motorcycle Tubes are strong. Now, STI has released the all-new UD "Ultra Heavy Duty" tubes that utilize a nearly bombproof 4 mm thickness. Top quality and ultra heavy duty performance at an affordable price make STI motorcycle tubes stand out from the crowd.

Tube Specifications:

  • Size: 110-120/90-19.
  • Valve: TR-6 (straight metal stem (8 mm diameter)).

Great Quality and THICK

These are super thick tubes! They hold up to rough riding and terrain. I have yet to ruin one from rough rocks. Did rip one after riding on it for 80 miles as I had a bad rim lock and it eventually cut through the tube. But took it 80 miles to get through there.

Tried to fix on trail before I knew it was ripped. Shows how think they are

Great tube !

This is a great 4mm thickness tube to purchase for the price but mainly the durability it provides the tires and keeps your bike running rather then repairing.

Will this tube fit a 120-80-19 tire?
I have a 2009 kx450f with a 120-80-19 rear tire and I was seeing if this tube fits it

Yes, this tube will work great in your 120/90 tire as long as it is an 18 inch tire. If it is a 19 inch tire then this tube will not work.
