Masomo Monday – TSD ( Total Stopping Distance)

Category : Masomo Monday

Total Stopping Distance is a sum of 3 parts.
1. Perception Distance
2. Reaction Distance
(1&2 are referred as Thinking Distance)
3. Braking Distance

Actual thinking distance varies according to the speed of the bike, your physical and mental condition, your attentiveness and whether or bit you were expecting something to happen.

Good anticipation gives you more stopping distance. Anticipation is much more important than fast reactions. It takes much longer to react to unexpected events than to expected ones – you need less thinking time if you are anticipating events and not just reacting to them.
In the video attached, the rider is not exercising restraint speeding on a two way country road , putting himself and others at risk.

1. Perception Distance
He did not anticipate any hazard in any of the near blind corners on this road, the presence of the truck catches him by surprise. He was in the wrong lane position as he came into the turn, limiting his view through the out the corner. He is still moving and this eats into his braking distance.

2. Reaction Distance
His reaction time is delayed, he takes time to process the truck coming into view. He is still moving eating into his braking distance.

3. Braking Distance
At the speed he is still travelling at his braking distance is limited. He grabs hard onto his brakes. He has lady luck on his side, and squeezes between the truck and the pavement. And his ABS kicked in which prevented his wheels from licking and the bike going into a skid. The scattering noise you hear is the ABS constant release at lock point to brake again. Though in review ABS did increase his braking distance.

Question.
What should he have done different to avoid putting himself and others at risk?

Want to become a better rider?

You can read books, ask friends for help or practice the stuff we talk about here on InkedBiker Riding School. But, without exception, the most effective method is to get yourself to a track school. Here’s the best performance motorcycle riding schools in Kenya.

 

 

Our Mission

Having the Country’s best organized and most professional riding school is our goal. But having our students leave with a better understanding of the cornering process, fewer uncertainties about it and a good measure of their confidence restored, is our day-to-day focus — it’s also the standard by which we judge our own performance
