Product number: RS11139 Chain size: 520 Number of teeth: 39 Material: Aluminum (A7075-T6/Super Duralumin) Representative model: Grass Tracker/ST250/VOLTY

From the viewpoint of cost and durability, most normal sprockets, except for some competition vehicles, use very heavy sprockets made of steel. In order to bring out the performance of your car, aluminum is the best material for sprockets. The weight is approximately 1/3 that of steel. Since it rotates at extremely high speeds, it is essential to reduce weight. The shape is designed to prioritize performance and design over cost, so you can expect it to dress up your car. [Compatible models] SUZUKI / Grass Tracker / Grass Tracker BIGBOY / ST250 / VOLTY [Note] - When changing the number of teeth, please be careful of interference with the car body and chain length. The number of teeth set by the manufacturer does not guarantee that it can be installed on the vehicle body. Caution (Disclaimer) > Please read -
