Supersprox makes their Rear Aluminum Sprockets from a tough 7075 T6 aluminum alloy that makes them both strong and lightweight. With Supersprox, youâ€re getting a refined sprocket because they focus on details like the self-cleaning grooves between every tooth that shed debris, and the corrosion resistant anodized finish that matches your factory colors. But, Supersprox lets others do the talking for them. And with their sprockets being used by AMA Supercrosser Mike Alessi and as OEM parts by KTM, Honda, and Husqvarna, thereâ€s no shortage of people willing to speak up.
