Ensure a stable, responsive ride with this premium universal 17-inch front inner tube. Constructed from high-grade butyl rubber, this tube is specifically engineered to provide maximum air retention, excellent structural elasticity, and enhanced puncture resistance for daily street commuting, highway cruising, or light trail riding.

This highly adaptable front inner tube is designed for 17-inch wheels running a metric 70/90-17 tire profile, and it serves as an exact crossover fit for traditional imperial sizes, including 2.25-17, 2.50-17, and slim 2.25/2.50-17 combinations. It comes equipped with a heavy-duty, threaded TR4 straight metal valve stem, complete with a lock ring and valve cap, ensuring a rock-solid anchor to the rim to prevent stem shearing and make inflation effortless.

This tube is an ideal stock front replacement for popular retro step-through mopeds, classic cubs, lightweight commuter street bikes, and modern small-displacement scooters.

Fitment & Size Compatibility

This versatile 17" front tube spans multiple metric and imperial tire designations, making it an excellent staple for garage inventory.

Size Cross-Reference:

  • Metric: 70/90-17
  • Imperial (Inch): 2.25-17, 2.50-17, 2.25/2.50x17

Common Vehicle Fitments:

  • Scooters & Retro "Cubs": Matches the standard front tire profile for classic Honda Super Cub models (C50, C70, C90, Passport), modern underbones, and international lightweight commuter scooters.
  • Mopeds & Lightweight Street Bikes: Fits a vast array of vintage and modern small-bore street platforms, vintage mopeds, and motorized custom builds utilizing slim 17-inch spoked rims.

Key Features & Bullet Points

  • Targeted Front Fitment: Engineered specifically as a slim profile, lightweight 17-inch front inner tube optimized for nimble steering and reliable tracking.
  • Premium Butyl Rubber: Formulated from high-quality butyl rubber rather than standard natural rubber, offering superior resistance to pressure loss, sidewall aging, and pinch flats.
  • Threaded TR4 Valve Stem: Features a rugged, straight metal TR4 valve stem that locks firmly into the rim hole, preventing the stem from pulling or tearing during low-pressure scenarios or hard braking.
  • Broad Sizing Crossover: Easily matches both modern metric 70/90-17 configurations and classic imperial 2.25-17 or 2.50-17 requirements.
  • Heavy-Duty Construction: Built with uniform wall thickness to eliminate thin spots, providing a dependable shield against flats during tire lever installation and daily road use.
