Inner Tubes

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.

STI Motorcycle Tubes are strong, stronger, strongest. The HD “Heavy Duty” model is 50 percent thicker than most standard tubes on the market today. The HDs are made from high quality butyl rubber with a 2mm thickness. STI’s XD “Extreme Duty” butyl rubber uses a 3mm spec, making it 30 percent beefier than most heavy duty tubes now available. The XD is specifically designed for severe applications and has already been proven in off-road competition. Now, STI has released the all-new UD “Ultra Heavy Duty” tubes that utilize a nearly bombproof 4mm thickness.

STI Motorcycle Tubes are economical. The HD, XD and UD models are priced considerably less than comparable rivals. STI has earned a reputation for delivering remarkably high-value tire and wheel products, and that philosophy certainly applies in this case as well. Top quality and performance at an affordable price make STI motorcycle tubes stand out from the crowd — as does their rugged, attractive packaging.

Motocross Action Magazine recently awarded these tubes with a 4-star rating. To view the product test, click here.

STI Motorcycle Tubes are in stock now at all STI warehouse locations, in a wide variety of sizes for all models.

They are available to dirt bike riders at finer powersports dealers everywhere, through MTA Distributing.
