Heavy Duty Motorcycle Inner Tubes

The front wheel of a dirt bike handles both steering and shock absorption. If the front tube bursts, the rider can crash severely. That's why we designed this heavy duty motorcycle inner tube specifically for the front wheel. Available sizes are 80/100-21 and 90/90-21, which are standard 21-inch front wheel sizes for dirt bikes. Wall thickness ranges from 1.2 to 1.5 mm, much thicker than typical front tubes. The valve root and joint area have been reinforced to handle bigger impacts. Valve is TR6, thicker and stronger than standard, and recommended air pressure is 2.0 to 2.5 bar, with 2.5 bar being common for the front.

Our factory has 16 years of experience. We collaborated with a professional dirt bike team in China, who reported that front tubes often crack at the valve root. We improved the valve vulcanization process to solve this problem. Monthly production capacity is 1 million units. Minimum order quantity is 10,000 pieces, and sizes can be mixed. We support OEM, and free samples are available; custom samples take about one week. Quality meets national standards, with full inspection before packing. Third-party inspection is allowed.

Warranty is 3 months. Payment terms are 30% in advance and 70% before shipment. We accept USD and ship DDP to your warehouse. Selling this heavy duty motorcycle inner tube for dirt bike parts gives your customers peace of mind.
