Kenda Heavy-Duty Motorcycle Inner Tube 80/100-21 (300/325-21) 2.5mm Tuff Wall TR-6 Valve

The Kenda 695H5222 is a heavy-duty 2.5mm Tuff butyl inner tube built for off-road and motocross wheels using 80/100-21 (300/325-21) tires, offering extra puncture and pinch-flat resistance compared with standard OEM tubes.

This reinforced motorcycle inner tube is engineered for riders who demand greater durability on rough trails and in race conditions. Made from premium butyl rubber and featuring a straight metal TR-6 valve stem, the Kenda Tuff tube delivers more material thickness where it matters to reduce the likelihood of flats caused by thorns, rocks, and hard impacts.

How does the thicker 2.5mm construction help on rough trails?

The extra wall thickness increases resistance to punctures and pinch flats without changing how the tire mounts or rides. Because the tube uses quality butyl rubber, it retains air well while adding a protective buffer between rim and terrain.

• 2.5mm Tuff wall is roughly twice the thickness of typical OEM tubes
• Improved resilience against thorns, sharp stones and abrasive surfaces
• Maintains air retention comparable to standard butyl tubes

Will this tube fit my wheel and work with my tire size?

This model is sized for 80/100-21 tires, which is equivalent to 300/325-21 in many sizing conventions. It’s made to fit standard 21-inch motocross and off-road rims that accept TR-6 straight valve stems.

• Designed specifically for 21-inch wheels and compatible tire dimensions
• Straight metal TR-6 valve stem for reliable inflation and sealing
• Typical fitment for off-road and motocross front wheel applications

How does the valve and material choice affect maintenance?

The straight metal valve stem provides a robust connection point for pumps and gauges, while premium butyl rubber is known for predictable air retention and ease of repair if needed. Together they make routine maintenance straightforward for trailside or garage service.

• Straight metal valve stem resists bending during inflation
• Butyl rubber holds pressure well and patches easily if damaged
• Compatible with standard tire levers and repair kits used by riders

How much extra weight or ride change should I expect?

The thicker Tuff tube adds a modest amount of weight versus ultra-light OEM tubes, but most riders will notice only a small change in feel while benefiting from fewer flats. The construction balances durability and rideability for off-road demands.

• Slightly heavier than thin OEM tubes to provide added protection
• No special rim modifications required
• Optimized for durability without compromising basic handling

Who is this for: The Kenda 695H5222 Tuff inner tube is aimed at motocross racers, off-road enthusiasts, and trail riders who want a stronger, more puncture-resistant tube for 21-inch wheels. If you frequently ride rough terrain, confront debris, or prioritize fewer roadside repairs, this beefed-up butyl tube is a practical upgrade over standard OEM options.
