I installed this product on my DUCATI MONSTER S4, and I can say that AFAM is the only sprocket for DUCATI in early 2000's. It is the same European product as DUCATI, and it is used for DUCATI as OEM parts. And, my favorite rider, Carl Fogarty won WSBK in 1995 with AFAM sprockets.This time, I bought 40T (STD: 37T), which is 3T up. Along with this product, the front sprocket and chain are being replaced at the same time.Since I have just replaced them, I cannot say anything about the performance, but due to the fact that I have replaced them with 40T, even in 3rd gear, I can wheelie just by operating the throttle.

AFAM's aluminum rear sprocket is a high performance bike sprocket machined from A7075, a super duralumin material used in the manufacture of aircraft, and T6 processed (hardened heat treatment process).
In addition, in order to increase the hardness of the surface, the sprocket surface is hard anodized with a film thickness exceeding the standard, which is 1.5 times higher than that of conventional anodizing, to achieve superior hardness and durability.
In addition, the weight of the sprocket can be reduced by approximately 65% *1 compared to the stock sprocket.
The off-road sprockets are equipped with grooves called mud grooves to prevent the chain from clogging and to allow mud to drain quickly.
