They came stock on my bike when I got it a year ago and I still have them on 11k miles later. They are okay, no real complaints about them. I'll have a better idea of how they work after I replace them and have another set to compare them to.
They are pretty good, wouldnt use them for the track, but I hav went through some twisties rather fast with them. I have 7000 mi on them and they are still good as new. If your just going to be touring, they're great. Anything more aggessive than that would b safer with a sportier, stickier tire.
The stock BT-020 are very long lasting. I had only approximately 7500 miles and it was barely staring to show some flattening. I estimate it would probably last up to 15K miles. As far as grip and handling goes, I have tried Dunlop Sportmax tires and its profile is much more pointed and compared to the stock Bridgestones, the stock tires have a very predictable tip in while the dunlops just seem to drop into turns with little effort.
Thanks, yes they were replaced by the BT021's but I got a pair of BT020's given to me with the bike. They are new and uninstalled. The Dunlop Sportmax D252's that came OEM are pretty much shot after only 7500 km.
