Shinko 87-4040 009 Raven Radial Tire

Definitely a harder compound than the Dunlop Q2’s I had previously. I was concerned about the cornering grip, so with some hesitation, I ran these (front and rear) at back to back trackdays at Texas World Speedway on 05/09 & 05/10. I run intermediate lap times (2:20) and had no problems with dry track grip. They were very slippery on the “tar snakes” in the rain, but I’m not sure any tire would have done much better in those conditions. Both front and rear did not ball up as much as the Dunlop Q2’s, with the rear hardly at all.I’m looking forward to see how the longevity of the tires are. The trackday was ridden after 2200 miles of street riding on the rear and 700 miles of street riding on the front. I’m asking alot out of a tire, long life on the street, and good grip on the track. These are doing great so far.Update: I’ve just replaced both front and rear tires. I got 6,100 miles out of the rear and 6,900 miles out of the front, including three track days. The front still had considerable tread life, but switched both to Dunlop Q3’s for more track grip, although I never tucked the front with the Shinko.

I have a well used set of these on my 330lb 2009 KTM Duke 690 and they stick to the pavement very well in wet or dry conditions, 29 psi front/back. I love them very much!I also have these on my 430lb 2009 Ducati Monster 696 and I have to use more psi to get it to feel as firm as my Duke. I’m up to 30/29 psi as I only go up incrementally, but I feel that I might bend my front rim on this rough riding bike (with overfilled forks) on crappy Shreveport/Bossier roads in LA. I’ll try 32/30 this weekend. I have no problems with grip, but I’ve yet to ride this hot-box bike in the rain with these tires.And yes, I’ll be buying another set for my 430lb 2008 Suzuki SV650. I thi
