Description
Product Overview
The Caltric Red O‑Ring Drive Chain & Sprockets Kit is a complete drivetrain solution designed specifically for Honda TRX400EX models produced between 1999 and 2004. Crafted from high‑grade hardened steel, each link is precision‑machined to provide smooth power transfer while resisting stretch and fatigue. The included O‑rings are made from durable synthetic material that seals each link, preventing dirt, water, and debris from entering the chain, which dramatically extends service life. The kit contains a front sprocket, a rear sprocket, and a full‑length O‑Ring chain, all finished in a striking red color that not only adds visual appeal but also makes wear inspection easier. Dimensions and weight are optimized for the TRX400EX, ensuring a perfect fit without the need for additional modifications.
