PIVOTRAX 2.50/2.75-10 Heavy-Duty Inner Tube — 2mm Butyl, TR4 Straight Valve for 10" Pit & Youth Bikes

PIVOTRAX 2.50/2.75-10 (80/90-10) heavy-duty inner tube made from 2mm butyl rubber with a TR4 straight metal valve delivers rugged, reliable air retention for 49cc–70cc pit bikes and youth motocross bikes.

This reinforced inner tube is built to handle off-road riding, track sessions, and everyday trail use on small-displacement bikes. Engineered for compatibility with common 10-inch wheels, it replaces worn or punctured tubes on machines like the Honda CRF50/XR50, Yamaha PW50/TTR50, Suzuki DRZ70/JR50, Razor MX650, and many Baja or Coolster models. The combination of a thicker butyl wall and a heavy-duty TR4 valve reduces flats and makes pump-ups and frequent tire swaps easier and more dependable.

Will this inner tube fit my 2.50/2.75-10 or 80/90-10 tire?

Yes — the tube is sized to work with both 2.50 and 2.75 width tires as well as nominal 80/90-10 sizing. It’s tailored for 10-inch rims commonly found on pit bikes and youth dirt bikes. Always double-check rim diameter and recommended tire width in your owner’s manual before purchase.

• Fits tires labeled 2.50/2.75-10 and 80/90-10
• Designed for 10-inch rims used on 49cc–70cc bikes
• Compatible with Honda, Yamaha, Suzuki, Razor, Baja, Coolster models listed

How does the 2mm butyl construction improve ride durability?

The 2mm reinforced butyl rubber adds a thicker wall that resists punctures and slow leaks better than thinner tubes. It dampens small impacts and reduces pinch flats when hitting obstacles, giving more consistent air pressure through rough sections. That thicker material also helps the tube retain shape under load for steadier handling.

• 2mm butyl for improved puncture resistance
• Better shock absorption over roots, rocks, and curbs
• Reduced risk of pinch flats during off-road riding

Why choose a TR4 straight metal valve stem for pit bikes?

The heavy-duty TR4 straight metal valve stem is built to endure repeated inflation and higher pressures without bending or leaking. Its seamless connection to the tube lowers failure points and makes it suitable for frequent tire maintenance common with racing or trail use. The valve’s length and thickness also fit standard pump heads and compressors reliably.

• TR4 metal valve for leak-resistant inflation
• Resists bending during wheel removal and installation
• Works with common pump heads and air tools

What performance should I expect on the track and trails?

You can expect more consistent air pressure, fewer roadside flats, and steadier handling during cornering and acceleration. The reinforced tube reduces downtime from punctures and helps maintain predictable tire behavior over varied terrain. It won’t prevent every puncture, but it significantly lowers the frequency of flats compared with standard thin tubes.

• Consistent air retention for longer sessions
• Improved handling stability under load
• Lower maintenance between rides thanks to fewer leaks

Who is this for: Riders of small-displacement motocross, pit, and trail bikes who want a dependable replacement inner tube that balances durability and compatibility. It’s ideal for parents buying spares for youth bikes, track mechanics who need dependable replacement parts, and hobbyists who ride off-road regularly. If you own any of the listed models or run 10-inch wheels and want fewer flats with easier inflation, this PIVOTRAX tube is a practical upgrade.
