High quality replacement rear sprocket for Motocross bikes.

Renthal ultralight rear sprockets are manufactured to extremely high tolerances from a special material developed to withstand the rigours of supercross, motocross and enduro racing.

The 7075 T6 aluminium alloy rear sprockets are 66% lighter than steel, yet incredibly durable.  Their advananced tooth profile, conscentricity and accuracy of fit provide maximum power transfer and long life.

Renthal's combination of a very high strength base material and an excetionally hardwearing surface result in significantly increased sprocket life over other brands.
