50-Tooth JT Steel Rear Sprocket for Kawasaki KX/KXF 125/250/450

Boost the performance, durability, and reliability of your Kawasaki KX or KXF drivetrain with the JT Steel 50-Tooth Rear Sprocket – the premium steel rear sprocket that fits perfectly on Kawasaki KX 125, KX 250, KXF 250, and KXF 450 (all model years)!

JT Sprockets is globally renowned for its extremely strong, long-wearing sprockets. This 50-tooth rear sprocket is crafted from high-quality hardened steel with a thick, robust build. It strikes the perfect balance between durability and weight. The 50 teeth deliver slightly lower gearing than a 49-tooth sprocket, delivering more sand traction, better corner exit acceleration, and reduced wheel spin – ideal for sand tracks, deep mud, or when you want more low-end punch.

The teeth are precision-machined for a perfect chain fit, extending your chain's service life and reducing stretch. Thanks to its high-quality steel, this sprocket wears slowly, even during intense motocross use.

Whether you're racing competitively, training daily, or fully upgrading your KX/KXF, this JT 50-Tooth Steel Rear Sprocket is a smart, durable choice that takes your drivetrain to the next level.
