I recently mounted new Shinko 705's on my V. The other day I made a left turn by mistake and my riding partners continued straight, so I immediately U-turned and then I turned left back onto the main road. This was a wide (2 lanes in each direction), clean, well maintained state route and as I leaned into the turn, I probably added too much throttle. It felt like the bike's rear end was drifting out. This was all a very comfortable sensation - not scary in the least.

A couple of points. I am not a 'hot' rider by any means; I prefer to ride slower thru the twisties so that I can SEE and enjoy the country I am riding through - not get the adrenaline pumping by carving the turn as fast as possible. My other ride, an ST 1300 will, when I hit a painted line or tar snake on the road and am leaned over in a fast curve, slip on the paint in a fast skid (I have Pirelli Angel GT's on this bike). This lateral 'drift' is not pleasant, is only the 4 to 6" width of the paint, is over almost before I know it, and is a marked contrast to what the V Strom exhibited.

The Shinko's are obviously not high performance street (only) tires, and had about 250 miles on them. It is possible they were not fully scuffed in and I was over onto the new rubber.

Has anyone else experienced this kind of behavior on the bike? With these tires? Obviously I am going to be more careful w/ that throttle in tight curves in the future, but this experience sort of reminded me of what I did on my bicycle 40 or more years ago.

Yeah, I've done that dog tired, bike loaded with camping gear and a Porche on my tail. His drifting sounded a lot more expensive than mine - I could hear the gravel hammering his car when he stepped of the seal.

As you said, it was quite comfortable though in my case the fact my reflexes were slow due to tired may have contributed to my survival.

I have about 2000 miles on a set of 705's.

(Edit: on a 1000cc, not a 650)

I've had them off road and took my time breaking them in, progressively leaning more and more. On dry ground below 90MPH they seemed well planted.

I can't recall them doing as you described, but I have had them spin first part of a wheelie as if the clutch slipped then grabbed. Tire wasn't fully up to temp, 60F out and only 2 miles into the day. I wasn't able to repeat after that.

Shortly after I switched over to my 804/805's, and oddly, they did seem to hold better in all situations, which leads me to think maybe the 705's are a tad greasy on the road?

Havnt put the 705's back on yet, and I'm out for most of the riding season on a blown ACL.

I would say it is very unusual for a 650.

I have a couple of favourite roads where I could get my old Wee to break traction.

I had dropped one tooth from the front sprocket that gave the bike a some more pep but it still took a big determined effort to get the rear to spin up, though I have never used Shinko's

Good luck with your recovery - I hope it goes quickly.

Thank you all for your replies. I should add, the PO put a 17 tooth front sprocket on the bike, which should have reduced my available torque (while dropping revs at highway speeds) when I poured on the gas in that turn. I'll just pay more attention to what I do on these new tires as I get used to them.

Sometimes understanding how "block" style tires behave is helped by looking at the extremes, like full knobbies. On the street full knobby tires "walk" sideways. Each row of knobs hold traction and bends until they can't hold anymore lateral force. They break traction which gets caught by the next row. Wash / rinse / repeat. Because the rows are staggered with gaps in between, the bike creeps sideways (in an arch).

Adventure tires behave the same way, just not as dramatically or as quickly. This notion of a tire "walking" in a constant rate is actually very helpful. It is like someone tapping you on the shoulder and telling you, Psst, that's about it.

Then comes the other factors such as carcass design and rubber compounds. It is often a matter of economy. Carbon-black is less expensive than silica, etc. Bridged blocks and multi-layered designs are more expensive. For me, I appreciate a tire that calmly lets me know when the conditions and my behavior are approaching the limit as opposed to no warning. When I choose tires and cost is an issue, I ask myself if in that last .005 seconds _ should I have spent that extra $40.

FWIW. I drifted my DL650 with excessive speed and knobs on, power had nothing to do with me losing traction.

Probably 30kph faster than I should have or would have taken that corner normally. Fortunately the rear was quite forgiving and the front had more grip than the rear, so nothing really frightening happened just "Oh, the back is coming around", I just carefully didn't add power until the corner straightened out some - and as noted above the car behind me had even more fun and he had good road tires on so the K60's performed very well in absolute terms.

Only tires I ever drifted were IRC's on a '74 Honda 500. the freeway off ramp going home every night. No other tire has acted like that since. I've been running 705's for a long time now on two bikes. Never had that sensation but I have dragged pegs on occasion.

I've been running 705s on my '12 Wee for the last 3 riding seasons (replaced the OEM Trailhawks).

Two sides to the coin...

I was recently in a BRC2 training class run by a HD dealership. Most of the other participants had Harleys or other cruisers. On many of the stopping exercises I was skidding my rear tire, which resulted in some extra attention from the instructors. At one point, an instructor pointed out that my combination of ADV-styled bike and rear tire choice (not a 100% road tire) was making harder for me than the others to prevent. That being said, I feel like if I put the time/money/effort into really setting up my suspension, it would help greatly.

When taking sharper corners at speed, I find myself regularly scraping my peg feelers. At first this concerned me, because I felt it was taking my dangerously close to washing out the tires. But it happens frequently enough, without disaster, that it's become more comfortable. The 705s seem to stick well enough in these situations. Again, this is something I could probably address with some suspension work.
