Dirt Tricks Chromoly Steel/Zirconium 50-Tooth Rear Sprocket for Honda CR Series

The Dirt Tricks CR-50-D-B rear sprocket is engineered for high-performance off-road riding, combining durability with lightweight construction. Designed by industry expert Greg Burns, this sprocket utilizes aerospace-grade steels and advanced heat treatments to ensure longevity and resilience. Its innovative design incorporates finite element analysis (FEA) stress testing, resulting in a product capable of withstanding an entire season of rigorous use without compromising weight or strength.

Constructed from a proprietary combination of chromoly steel and zirconium coating, this sprocket offers a significant reduction in friction—up to 50%—which enhances drivetrain efficiency and reduces wear on other components. The zirconium coating not only improves durability but also provides a sleek, black appearance that resists corrosion and maintains its sharp look over time. Its minimalist profile and lightweight nature make it two and a half times stronger than stainless steel alternatives, providing reliable performance under demanding conditions.

Specifically designed to fit a range of Honda models from the classic CR500R to the more recent CRF450RX, this 50-tooth sprocket is ideal for riders seeking a durable, high-quality replacement part. The product's advanced materials and coatings contribute to increased longevity and reduced maintenance, making it a valuable addition to any off-road motorcycle setup. Dirt Tricks backs this sprocket with a one-year guarantee, reflecting confidence in its durability and performance capabilities, and offering peace of mind to riders seeking a dependable upgrade for their bike.
