Do not use this function when riding on standard roads, only on special sites (e.g.
motorcyclist training centers).
5.6 Acceleration measurement
The MC 1812 has an acceleration measurement function.
The function ‘0...100/sec’ (default value) starts from standstill. During the
measurement, ‘calc.’ appears on the display. On reaching the target speed, the
measurement stops and the result is displayed in the format xx.x sec.
This function is used to record the motorcycle’s ‘real’ acceleration values.
The results can be deleted by pressing the Reset button.

MC 1812
5.7 Highway acceleration measurement
The MC 1812 has a highway acceleration measurement function.
This function ‘60...100/sec’ (default value) measures the time (or optionally
the distance – selectable in the basic settings) that the motorcycle needs to
accelerate from a lower to a higher speed.
The measurement starts as soon as the lower speed is exceeded. The
measurement ends as soon as the higher speed is reached. During the
measurement, ‘calc.’ appears on the display. The measurement result is
displayed in the format xx.x sec or optionally in m.
Note
Do not use this function when riding on standard roads, only on special sites (e.g.
motorcyclist training centers).
5.8 Braking measurement
The MC 1812’s braking measurement measures the braking coefficient ‘brake
(m/s²)’ and the braking distance ‘brake dist.’. The measurement is triggered
via a freely configurable minimum deceleration value (see basic settings). The
minimum deceleration is needed to prevent the braking measurement from being
triggered when the rider simply releases the throttle.
During the measurement, ‘calc.’ appears on the display. The measurement result
is displayed in the format xx m/s² for the braking coefficient and in xx m for the
braking distance. The speed range in which the measurement took place is also
displayed.
This provides you with information about your braking behavior so that you can
optimize it.
Note
Do not use this function when riding on standard roads, only on special sites (e.g.
motorcyclist training centers).
5.9 Drag race/quarter-mile race
The MC 1812 has a drag race function. The measurement begins from a
standing start. During the measurement, ‘calc.’ appears on the display. On
reaching a distance of quarter of a mile, the measurement stops and the result is
displayed in the format xx.x sec.
Note
Do not use this function when riding on standard roads, only on special sites (e.g.
motorcyclist training centers).
