BUY IT!
I've give only 4 stars due to never having used another. So, there could be better..however, i was happy about the delivery time and packaging. The quality is nice. And most important in my eyes..it was night and day after installation. My bike gets to speed much quicker, and since i hardly break 110 mph i don't even notice I've lost top speed.

Awsome looks and fitment
Got this set and when received it next day! Said oem replacement gave them a call and they sent out a replacement amazingly fast! Got the next one and started looking closer and saw it was my mistake of not seeing the label that showed sprocket count so dont make my mistake of not looking at the count and only looking at the big red label. Went on as chains normally go. It is the rivet type of masterlink and chain was already cut to length so no need to remove links! Oh front sprocket had to look up what side went against the nut so verify with your bike. Mine was the side with the numbers to the nut.
