Brake reaction times
• Brake reaction time (BRT) of motorcyclists was measured on a sample of 1,181 subjects, using stationary real motorcycles coupled to a computer.
• The mean BRT obtained by the group of test subjects, all classes combined, was 0.463 second.

Brake reaction times
• When the subject waited for the signal with fingers already poised over the brake lever and foot positioned over the brake pedal, the mean measured BRT was reduced by 0.154 seconds.
• At 100 km/h, an increase of 0.154 seconds represents an increase braking distance of 4.28 metres
