DescriptionJT. Steel Self-Cleaning 251 - 520 Sprocket

Product details :

Features

The JT Sprockets JTR251.48SC sprocket is a transmission part designed for off-road use. Machined from C49 steel, it features a black finish and a standard tooth count of 48 teeth with a pitch of 520. Its mud-resistant profile facilitates the ejection of mud and debris to minimize chain snagging in muddy or dusty conditions.

Manufacturer Reference: JTR251.48SC
Material: C49 steel
Color: black
Number of Teeth: 48
Chain Pitch: 520
Type: standard, mud-resistant profile

Designed for motocross environments, this sprocket is suitable for replacement setups or gearing modifications. It fits many machines equipped with a 520 transmission, including recent enduro/cross models such as the YAMAHA YZ 450 F (2026), the FANTIC XX 125 (2022), or the GAS GAS EC 300 F (2015). Be sure to check compatibility with your sprocket and axle before installation.

For optimal performance: check the condition and tension of the chain, lubricate regularly, and adhere to the recommended torque specifications during installation.
