## Abstract

A motorcycle includes: a front wheel brake that brakes a front wheel that is supported by a front fork; a rear wheel brake; a control unit that controls an ABS modulator connected to the front wheel brake and the rear wheel brake on the basis of front wheel speed and rear wheel speed; and a front wheel rise detection unit that detects whether the front wheel is likely to rise from a road surface, wherein when the front wheel rise detection unit detects that the front wheel is likely to rise, the control unit operates the front wheel brake through the ABS modulator.

## Claims

### Claim 1

A motorcycle comprising:
a front wheel brake configured to brake a front wheel that is supported by a front fork including a suspension;
a rear wheel brake configured to brake a rear wheel supported by a swing arm;
an ABS modulator connected to the front wheel brake and the rear wheel brake;
a control unit configured to control the ABS modulator on a basis of front wheel speed and rear wheel speed; and
a front wheel rise detection unit configured to detect whether the front wheel is likely to rise from a road surface, wherein
when the front wheel rise detection unit detects that the front wheel is likely to rise, the control unit operates the front wheel brake through the ABS modulator.

### Claim 2 (depends on 1)

The motorcycle according to claim 1, wherein the front wheel rise detection unit is a stroke sensor provided to the front fork and configured to detect an expansion and contraction amount of the front fork.

### Claim 3 (depends on 2)

The motorcycle according to claim 2, wherein when the expansion and contraction amount becomes more than or equal to a threshold, the front wheel rise detection unit detects that the front wheel is likely to rise.

### Claim 4 (depends on 1)

The motorcycle according to claim 1, wherein when the front wheel rise detection unit detects that the front wheel is likely to rise, the control unit calculates a damping amount of a front suspension damper using acceleration as a parameter.

### Claim 5 (depends on 4)

The motorcycle according to claim 4, wherein the control unit calculates the damping amount so that the front fork sags.
