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. 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.
