These tires are a downright steal. If you race competitively we would suggest you purchase a few and keep them on hand for when you need a spare set. If you are a competitive racer than we also suggest that you look into the other models in the Bridgestone range to see whether there is a tire that may be a little more specifically tuned to your needs.
Not precious- Many new track day riders suffer undue stress over the anxiety of crashing their beautiful, high-dollar, chrome and carbon laden street bike. Thankfully, it’s easy not to crash at a track day if you ride within your ability. So, if all you have is your pride and joy, go ahead and bring it to the track, but at some point when you start pushing harder, you may want a dedicated track bike that has less sentimental value.
