Shinko F009 Raven tires...a quick review
I bought a 2004 R1150RSL last week for a VERY good price. It needed a bit of love and the top of the list was tires. The rear Metzler Z6 was severely cupped and the front tire was on its last legs. This bike exhibited extremely poor handling. It simply would not stay down in a left hand turn. And following a line around a corner was nearly impossible. I was convinced it has major suspension or frame issues. But before I could deal with that, I needed new tires.
Not wanting to spend a fortune on tires, I did some research and found a company called "Shinko". A bit more research found that this is the former Yokohama motorcycle tire company. I've used Yokahama tires on my Porsche and my pick-up trucks for years. The Price of the Shinko tires was almost unbelievable.
A search led me to the new Raven F009 Sport Radial tires. Bike Bandit is my "go to" for tires and I was pleased to see they carried this brand. I ordered two tires on Sunday and they were at my door Tuesday AM! Both tires, including shipping (and using my AMA 10% discount available at Bike Bandit) came to $157.33!!!!!! (120/70ZR17=$58.49, 170/60ZR17= $80.99, Shipping = $17.85)
Now, for that price they must be Stinko tires...after all, we all know you get what you pay for. When the tires arrived I had a couple of motorcycle buddies over my house. We opened the box (yes, Bike Bandit ships tires in a box..nice!), and inspected the tires. They looked great.
I quickly mounted them up and balanced. The rear tire needed no weights. It was perfect. The front tire needed 1/2 oz to make it perfect.
Once mounted up it was off to the local empty parkinglot to scrub them in. A bunch of figure 8s and I was ready to go. I went to my local highway cloverleaf (a great place to test tires...:whistle, and started a series of loops, getting lower and lower as I went. The results were great handling and not a bit of slip or wiggle. I can tell no difference from these tires and Avon Storms (my current favorite tire) that are on my VFR or the Metzler Z6 that are on my Moto Guzzi V11 sport. After about 20 minutes of this it started to rain. Just a light drizzle. This was a perfect opportunity to test wet adhesion. Although it wasn't a downpour and I couldn't test hydroplaning (not that I'd want to!) I can tell you that the grip was excellent. No issues.
All the strange handling that this motorcycle was exhibiting completely disappeared. It was like it was on rails in the twisties and held a line perfectly. I've never experienced tires having so much effect on a motorcycle. Or maybe it was because I wasn't riding the bike as the tires changed over a period of time. I bought the bike with bad tires and experienced the results immediately.
Time will tell how this very inexpensive tires will perform in the long run. I'll keep this thread updated with wear and anything else that might help others with a buying decision.
Later!

Hi
When I used to courier 12/13 years back I used Yokahama Tyres on my GPZ and found they were fairly comparible to Perreli's for grip and wear but quite a lot cheaper. I eventually settled to Mitchelin though as they seemed to last a lot longer so dispite the price be just as good value mile for mile and as I was doing 1000+ miles a week not having to change them to often ws important!
It will be interesting how they perform as they get older, I am currently on BT21's and they rode wonderfully for about 6 1/2K -7K miles, when I changed them at 8k they needed it though!

Shinko
Great read! I used the Shinko Advance Radial tires on my 94 R1100RSL and have had great results. In May, my sons and I toured the Rockies (mostly in the rain). On the way, I got a puncture and because of the mountainous terrain I had to ride it underinflated until I could pull over. The tire was stiff enough to support me even though it was going flat. When I finally got to a wide spot to pull off I had damaged the sidewall. I plugged the hole and "limped" downhill for a couple of miles to a nice wide place and called for help. Fortunately I had a relative nearby with a trailer so we weren't delayed too long. I had to replace the rear tire with a Mettzler, but I will be replacing it with another shinko when the time comes.
