Countershaft sprocket question

I wasn't sure about the best place to post this question, either in the Wunderfest thread or revive an older gearing thread, so here goes; I just put on a 16 tooth countershaft sprocket on my 2013 690 enduro because of an upcoming trip with quite a bit of highway miles. The stock 15 tooth sprocket has the rubber "damping" pieces on both sides, and the KTM 16 tooth sprocket did not come with any and the ones from the stock one won't fit due to the diameter difference (the 16 tooth sprocket does have holes in it as if it could take similar rubber pieces).

What is the rubber for, NVH reduction? Do I need to look for similar pieces for the 16 tooth sprocket?. For now I am going to run it without any, and I think many aftermarket sprockets are solid anyway so you could not mount rubber on them. Thanks in advance for any info.
