My last set was Shinko 705 rear, poor mileage and a Heidenau Ranger front which was good but noisy.
Running Dunlop Trailmax Missions for the next set front and rear. They are very stiff and hard to install but I expect excellent mileage out of them.
As a former Shinko user I have come to realize their false economy. While Shinko's are generally less costly they also typically do not wear as long as a lot of the more premium competition. If you are paying shop to change cheaper tires more often you may very well be paying more over all and never have the benefit of a good tire.
I have used the beloved 705 on several motorcycles and the one thing the 705 (especially the front) does universally the same on all bikes is they kill any bikes handling. The 705 front slows steering so badly you clock it on a sun dial.
The only time I'll seek out 705's is if I am selling a bike and it needs tires and I want to spend as little money as possible while giving the bike the curb appeal of new tires.
