Sunstar Rear Sprocket 46T Gold Honda CRF250R 2004-2022 5-355946

The wear on your stock sprocket directly impacts power delivery, acceleration, and chain longevity. A worn 46-tooth rear sprocket sacrifices efficiency and forces your drivetrain to work harder, reducing overall performance and increasing maintenance costs. The Sunstar 46T Gold delivers precision engineering and durability to restore optimal chain engagement and maximize power transfer to the rear wheel.

Built from aerospace-grade 7075 T-6 aluminum, this sprocket combines featherweight construction with the strength needed for serious riding. The exclusive tooth-valley design expands chain contact by 50%, translating to smoother acceleration and more reliable power delivery across the RPM range. Computer-optimized weight reduction holes keep rotational mass low without sacrificing structural integrity—a critical advantage on a lightweight machine like the CRF250R.

Installation is straightforward: this is a bolt-on replacement that fits Honda CRF250R models from 2004–2022 without modification. Hard anodized coating resists corrosion and wear, while integrated cleaning grooves minimize buildup and extend service life. Whether you're racing or riding hard on the weekend, this sprocket delivers the precision and durability that separates quality components from everything else.
