Description
A worn or damaged front sprocket directly impacts your ATC250R or TRX250R’s acceleration, chain wear, and overall drivetrain efficiency. The Renthal 13T Front Sprocket delivers the precision engineering and durability required for consistent performance whether you’re racing or pushing through challenging terrain. This is a direct replacement engineered to restore your bike’s power delivery while extending the service life of your entire drivetrain.
Renthal’s 655M13 nickel-chromium steel construction provides the hardness needed to withstand the demands of high-RPM riding and abrasive trail conditions. The precision CNC-machined design ensures zero runout and a perfect fit with your 520 chain, eliminating the slop that causes premature wear. Self-cleaning mud grooves at each tooth prevent debris accumulation, which is critical for maintaining traction and reducing chain slip in muddy or gritty environments.
At just 5.6 ounces, this sprocket won’t add unnecessary rotating mass to your bike, keeping your acceleration crisp and your handling responsive. Installation is straightforward—this is a direct bolt-on replacement requiring no modification or special tools.
