4. Drag race timing
The V-Gauge Lite provides a system for measuring motorcycle performance by timing 60ft, 330ft
(1/16mi), 1/8mi, and 1/4mi distances. It also records the speed and gear position for each.
The 0-60mph time as well as the actual RPM shift points are also automatically recorded. The
times are measured in 1/10 second increments since the V-Rod ECM reports about 12 speed
readings per second.
CAUTION!
The drag race timing function should never be used on public roadways. For
your own safety and the safety of others,
never
exceed the posted speed limit.
The V-Gauge Lite is no substitute for a track timing system but it can be a handy tool for
measuring the effect of modifications on the bike’s performance. Remember that, since the
speedometer pulse sensor is in the transmission (not on the front wheel, for example), rear tire
spin will cause incorrect distance readings. Also, the accuracy of the drag measurements is only
as good as the speedometer calibration.
