Crashed bike


That there was a fine seat of the pants analysis, Amigo!
Mostly based upon your apparent Vukcan mind-meld with @Rocket_Rider.
The response will undoutedly be that the road was sanded because of the down motorcycle hemorraging the fluids foynd on the road surface.
 
A long time ago, riding a Honda 305 on a rainy day. Came to a turn with a crown and a very smooth surface. I don't remember if I hit the brake or not, the rear end slipped down on the crown, it was quite a steep crown as I recall, and down I went. Fortunately slid off the road and onto somebody's front lawn. Wasn't going fast at all, 30 or less I would think. I've come to notice that here in Maine. many of the rural roads have a steep crown to them. Looks to me they did a bad job of widening the road.

Another time riding the Bonnie, hot day, tried to power thru a sharp turn, kind of slowly, hit the center oil strip and the 994 slipped out, caught the better pavement and whiplashed me, but I didn't go down. Still scary though.

So some things that I am really aware of now are the above and steel man hole covers, larger painted areas on roads, loose sand and gravel in the spring and after heavy rains. Condensation on parts of roads happens alot too in shaded areas, on the east side of hills.

Ride safely,

Accepted. The alternate would be that the oil, which caused the wheel under acceleration to step out, ended.
While stepped, out the clear dry pavement provided a sudden increase in friction which allowed the tire(s) to regain traction,

On a slick surface, I see no advantage in shifting to second early. Shifting/clutch will cause some degree of disruption to the rear tire rotational velocity. This increases the opportunity for a break in traction, especially true if transitioning between two surfaces with a large disparity in friction values. Steady slow acceleration is best. On those grated bridges, I find a diagonal line across just your lane works best. It exposes more of the metal surface to the tire.
 

I assume you were negotiating a left turn.
This is termed an off-camber turn. They are extremely dangerous, evidence of poor road engineering, and cause of many commercial truck roll-overs.
