Would be excellent as a spare or replacement for your YZ or WR, or to change your gearing. Here is some information from the Renthal website:
The longest lasting most durable off-road sprocket you can buy developed over 5 years.
The unique flat face design keeps weight to a minimum and means the TwinRing's as narrow as a regular chainwheel.
Inner Ring is high strength Ultralight 7075 T6 Aluminium. Outer Ring is Electroless Nickel Coated steel
Outer is expanded at 200 °C and then fitted to inner, creating a permanent bond for the life of the sprocket.
