1. Good looking & performing sprocket
I'm new to changing out sprocket's and chains, I just did that recently and I'm very pleased, I should have done that many years ago, not only on my 15 R1 but on my 06 GSXR, & 07 Hayabusa, both of which I bought new.
This sprocket looks good & performs very well, I don't know enough or have experience with performance sprockets to be able to give advice, but i'm not stupid either. I have trusted the information from STG since I found them in 2015 when I bought my new R1 & go with their product brands since. I think they have the best install videos, I have been very pleased dealing with STG.
