DURO Tire - HF903 - Front - 90/90-21 - Tube Type 25-90321-90-TT

If you're running a dual-sport bike or adventure machine that sees both pavement and unprepared terrain, the DURO HF903 delivers genuine versatility without compromise. The aggressive tread pattern excels on loose surfaces—dirt, gravel, and deteriorated roads—while maintaining predictable grip during street riding. You get a tire engineered for the 60/40 split lifestyle, not a watered-down jack-of-all-trades.

This is the tire choice for riders who refuse to swap rubber between their weekend trail runs and weekday commutes. The tube-type construction pairs with robust sidewalls to handle the abuse of mixed-surface riding, while the S-speed rating ensures you won't be held back on open roads.
