From what I've been told, Shinko's are made in Korea using old Yokohama molds. Apparently they are not using Yokohama compounds, though.
I have run several Shinko's on street bikes. I used 712's on a CB 750 with great results. 10k miles and the front was good for another rear. The rears were getting about 2500-3000 k miles , but I'm hard on rear tires. They never wore funny or took much balance. These were 18" rear and 19" front.
On another CB I ran their 009 Raven front and rear in 17". Again, they wore and lasted well. Both bikes were regularly ridden at 70+ mph and frequently saw triple digit speeds. I chose the Raven's on a friends recommendation after he got 12k miles out of a rear and his front with 15k miles looked very healthy still. That's great mileage for a sticky sport bike tire.
One thing I noticed about the Shinko's I've owned is that they were exceptionally grippy. My KLR came with 705's ( badly worn and cupped), but their dry traction was still fantastic.
Perhaps Shinko needs to toughen up their compounds if they want a good reputation selling DS tires. I can only say good things about their street rubber, but I read alot about knobs coming off. Sounds like too soft of a compound for such tall lugs.
From Shinko's website:
:Established in 1946, the Shinko Group began as a manufacturer of bicycle tires and tubes in Osaka, Japan that today has become a burgeoning manufacture of rubber products.
In 1998 the Shinko Group purchased the motorcycle tire technology and molds from Yokohama Rubber Co., and began production of these products under the Shinko Tire brand. With manufacturing based in South Korea and design based in Japan, the company has seamlessly combined Japanese engineering and design principles with South Korean production and quality control standards. Today Shinko Tires produces approximately 200,000 motorcycle tires per month.
In the United States Shinko Tires are imported by Western Power Sports, Inc. (WPS), with corporate headquarters in Boise, Idaho. With a strong foothold on the power sports market, and with warehouses located in Boise, Idaho; Fresno, California; Ashley, Indiana; Elizabethtown, Pennsylvania; Midlothian, Texas; and Memphis, Tennessee, Shinko Tires USA-in conjunction with WPS-is proud to bring you the Shinko line of Sportbike, Cruiser, Scooter, Off road, and Dual sport tires."
