Engineered for confidence on varied terrain, the TIRE 421 SERIES combines a tough construction with a traction-focused tread to keep you rolling—on trails, tracks, and around the camp.
Its durable nylon carcass resists punctures and impacts, while dimpled knobs bite into loose soil, gravel, and hardpack. An open tread pattern sheds mud quickly to maintain grip and steering precision in wet or sticky conditions.
Whether you’re exploring trails or commuting short stretches between rides, the TIRE 421 SERIES delivers reliable grip, predictable handling, and long-lasting performance in a compact, mini bike–ready package.
