Features

Zero's RX-1N shows battery level in 11 increments.

It's relatively effective to treat each increment as representing 9% of charge state, and do a little mental math to figure out that each increment could represent 6-12 miles (for say 2013), and work out the remaining range / speed tradeoff from that.

• go slower to get closer to 12 miles of range per increment
• go faster if you can afford to burn off the battery to reach your destination in time.

The Koso instructions linked below show how to operate it.

Speedometer Adjustment Quick How-To

• Reference

1. Turn on motorcycle.
2. Press and hold the Select + Adjust buttons simultaneously for 3 seconds.
3. Use the "adjust" button to increment the digit, and the "select" button to navigate to the next digit.

• The stock setting (for 2013) is 1972 28-132 2P.
• The previous setting (for 2012?) was 1972 25-128 2P.

Connections

Koso connectors are much simpler than Zero's connectors to its own custom dash.

Interchanging them would be a significant project.
