Oh dear, a rural left hand bend crash at 27mph!
Sergeant Breeze has not asked quite the right question. Rather than asking how you correctly assess corner entry speed, I would ask why this poor chap chose this particular corner at which to crash?
You could safely assume that this was not the first corner he encountered, so what was different about this corner compared to all the ones he had successfully negotiated before? Just looking at the picture of the aftermath we can see that there are chevrons in both directions and from the point where the photographer was standing, we can see that this corner was quite long. Sadly the photograph does not tell us if there were any more chevrons before or after the ones we can actually see, so we do not know the full extent of the corner or the road leading up to it.
Looking at where the car stopped, I would say that whatever went wrong, our rider got a spot of target fixation on the telegraph pole and sailed towards it and would have probably hit it, had the car not got in the way first!
So then, a classic rural left hand bend accident, made even more poignant by the fact that it happened at a stupidly low speed. Makes mincemeat of the idea that you slow down and enter the bend at a speed you’re happy with as you probably couldn't go much slower than 27mph if you tried.
One day, the Police will investigate accidents properly and perhaps will let us know just exactly what is going wrong in rural bends, but I wouldn't hold my breath.
In my younger days I had this exact crash, only in suburbier. The mistake I made was nothing to with speed. It was to do with target fixation. Not on the oncoming vehicle, but the mini skirt and heels walking up the opposite side of the road.
Basically, as soon as I slow down, I get bored and my eyes wander.
Take a 57mph bend at any speed, if you are not focused on the vanishing point, your gonna drift off line.
Of course, we also don't know if the the rider's entry speed wasn't alot higher and just 27mph at the point of impact.
I don't believe the 27 mph. That was calculated from the distance the rider travelled after impact, which could have been reduced by many other factors, including contact with the car taking out most of the energy of his forward travel. On a bend like that, if you take it at 27 mph, you would be wobbling round like a learner, more in danger of falling off due to lack of forward motion than drifting offline and hitting a car. It''s a classic example of the bike being far more capable than the rider believes. He thought he was going too fast, braked and stood the bike up. That's not a criticism of the guy. I suspect most of us are not as good as our bikes, and we've all done that at some point.
if your vanishing point goes away from you on bend then it is a safe speed or can even accelerate more ,.....if vanishing point comes closer to you then you need to decelerate till the vanishing point is neither coming or going away from your point of view ......
as said and practiced by motorbike cop on the bikesafe course attended .would recomend to all, and in most counties it is free or highly funded so cost is minimal....
