I installed the Shinko tires on my bike and like them better than the OEM tires. It takes a while to get used to knobby tires on the road but the grip is much better than you would think. The handling of the bike was very different compared to the OEM tire. But I have to say I installed also 4mm Michelin Ultra Heavy Duty tubes with the new tires, so I could feel the weight of the tubes in the corners. After the first 200 miles you will get used to this. However I got 3 flat tires in 1500 miles with the OEM tire/tubes.... guess this will be much better now.
In the dirt the traction of the Shinko tires is good. Only the grip of the rear tire when when accelerating out of the corners is not on a top level, but I must admit this can also be a lot of fun :-) In the rain they are as good as the OEM tire or even a bit better. This was the proof how bad the OEM tires really are. If a knobby tire is as good or better in the rain as a street tire, you know that Dunlop made a bad job here.
They last very long, are not too loud and are cheap to buy. A very good tire for 50/50 use. I would recomend this to riders who what to do longer tours on and offroad. If you ride mainly on streets I am sure there are better options available, but for the mix of on and offroad tours, the Shinko 804/805 is an amazing tire !!!
