17+ FZ-10 Supersprox Stealth Rear Sprocket


Typically ships within 2-5 business days.


The Supersprox® rear sprocket is a patented hybrid design combining the best assets of aluminum and steel sprockets.  The teeth are steel to increase service life while the rest of the sprocket is 7075-T6 aluminum to save additional weight without adversely limiting strength.  The outer tooth ring is electro-less nickel coated carbon steel and is pressed onto the inner aluminum ring with a 200 ton press.  6T9 stainless steel rivets hold it all together.  This design is found on many factory race teams and has been used extensively on high-horsepower applications.

Available in both 525 (OE) and 520 configurations.

Made in Ukraine and Poland.
