Are you riding on roads with high crowns. On long trips with a lot of highway miles I have worn out the sides of the tire to where the it looks V shaped.
Some important information that I forgot to include. That front tire has only 10,000 mile on it. And of them mile's 80% is open road and 20% twisties. So there maybe 2,000 mile's of hard cornering on that tire so far and I don't think that there would be more than 500 miles of twitsies left in that tire.
On the flip side the grip is great in the corners. I can remember when we were in the snowy mountains and I was riding with the sports bikes in the twitsies. I was riding solo without the speed controller and I was riding hard....................real hard, but that tire did suffer. The tire suffered badly and I just went for a ride with a work mate to some twisties. Again the tire suffered badly.
So I was thinking that this tyre maybe too soft on the sides for a heavy bike. When I was in the USA there were a few times that I tested the front tire. One of the hardest test was with that Hoon rider Peter on the Tail of the Dragon. Man can he ride and that was on E3. So I know what tire is going to get the nod very soon.............................I will be going with E4's. They will take a bit of hard riding.
Sorry if I'm slow replying on this mate. Yes, that tire is showing some unfavorable wear indications. If you look at those little wrinkle lines outside the center section, they resemble a "cold tear" pattern that is a racer's nightmare. What it means is the tire is not at optimum traction temperature for riding aggressively and the tire is in danger of separating. Might not be the case but I've seen very similar evidence of this kind before.
As to the Excedra tire itself, there is a difference between running an 1800 and 1500 or 1200 models. The 704/709 is an 1800 only (radial) tire and I am sorry I am not familiar with what Bridgstone offers in the bias ply range for 1200/1500 bikes. However, I can tell you that I have complete confidence in them on my '09 under any circumstances, far more than what it came with (D250). But the E4 is really getting some solid following reports.
Simplest solution is to go with "what you know" or have suitable experience with. You know how you ride better than anyone. Em, you also have a pretty strong "left hander" turn bias
grab all the kicks you can baby, you only make this scene once!
