Supersprox Stealth steel-aluminum rear sprocket
General description
- designation: RST
- was made of two different materials:
- the core of the sprocket is made of extremely hard, yet very light aircraft aluminum - this material is about 70% lighter than steel
- the crown of the sprocket, on the other hand, was made of very strong nickel-plated SC-55 carbon steel with an additional hardening process
- in addition, the crown was covered with a double anti-corrosion coating called 2xZink in black color
- both elements are connected with each other by rivets, this provides strength in motorcycles with a capacity of up to 1400 ccm
- the aluminum core is available in several color versions, thanks to which the sprocket emphasizes the appearance of the motorcycle
