When Honda added an aluminum sprocket cover to the 2014, I thought it was a fantastic upgrade to the cheap (but not inexpensive) plastic cover on the 2013. I contacted Mr T and he got me one. Soon after he listed it on his site.
I think it's one of the best modifications I've done on my bike.
Some folks may pass on this upgrade because it is not a perfect swap. The bottom mounting hole does not line up. That bothered me for about 2 seconds. (I did let Mr T know, and he updated his listing)
Three silver bolts are included with the cover. Simply add a stainless nut and washer to the bottom bolt to fill the hole. Only you will know... (well, anyone familiar with the difference will know).
The cover is very solidly mounted using the top 2 bolts. It's not going anywhere. I just had the cover off to replace the countershaft sprocket and both bolts were still very tight.
Did I mention I love this modification? Go for it!
