Menu Display

You can choose your log using this menu.

Riding Track Display Window

Displays the riding tracks at the circuit.

Number displayed in white are corner numbers and blue squares are used to display the section numbers.

Time Window

Lap Time:Displays the approximate lap time for each lap.

The lap time for the current lap is displayed in red.

Section Time:Displays the approximate section time based on the position in the current lap.

The current section time information is displayed in blue.

Time Window

Lap Time:Displays the approximate lap time for each lap.

The lap time for the current lap is displayed in red.

Section Time:Displays the approximate section time based on the position in the current lap.

The current section time information is displayed in blue.

Riding Line Window

The red triangle displays the approximate position and direction of the motorcycle. The light blue line displays the approximate riding line, and the gray line displays the course. Since the riding line displayed is based on GPS data, there are times when the riding line will not be displayed over the course line.

Skill Graph

Vertical Axis:Displays the cornering force. The higher the position in relation to the vertical axis the stronger the cornering force.

Horizontal Axis:Displays the motorcycle’s level of stability. The further the position is to the right in relation to the horizontal axis the higher the level of stability.

The Av star indicator is used to display the average skill level for the entire riding time.

Number in circle displays the corner of the riding track display window.

Red circle with number:Displays the current corner.

Blue circle with number:Displays the current lap

Black circle with number:Displays other lap

See here for detailed skill graph information.

Detailed Skill Graph Information

Vertical Axis:Displays the cornering force. The higher the position in relation to the vertical axis the stronger the cornering force.

Cornering force: Speed, bank angle, and steering angle values are used to express a deviation value to show whether or not the values are in balance in relation to the corner radius.

Since this system does not incorporate sliding and drifting data, values are higher than they would appear during normal motorcycle operation. Please strive for smooth cornering harnessing the cornering force of the motorcycle without trying to control it in an unnatural manner.

Horizontal Axis:Displays the motorcycle’s level of stability. The further the position is to the right in relation to the horizontal axis the higher the level of stability. Motorcycle’s Level of Stability: A deviation value which expresses whether or not the motorcycle is being actively moved by the rider. Active and passive movements are detected with the value being higher when there is more active movement present. This system is capable of determining whether or not the motorcycle is being actively operated. Please improve the motorcycle’s level of stability by maintaining smooth handling awareness.

Riding type based on Av (average) position

1. Beginner with low cornering force and level of stability values

2. Intermediate rider capable of improving their level of stability value

3. Beginning motorcycle racer that uses force to over control the motorcycle

4. High-level expert with both forces in good balance

When each of the circles with a number are positioned close together, it shows that you have a consistent ability for cornering regardless of the type of corner.

When the numbers for corners are spread apart, it means that cornering was performed well on certain corners and poorly on others.

When each of the numbers are widely spread apart, it means that riding was not stable.

When the Av (average) star indicator is in a higher position further to the right, it can be said that the numbers are in a close range and that riding is at a good level.
