What type of riding are you doing on your CBR1000RR? Those tires are way below the typical performance level for tires that we see on these bikes. That may be a good price, but you are selling yourself way short in grip, feedback, turn in, etc if you put those on. Dunlop has many other great tires that cost more, but the performance/dollar ratio is way better.
