Brake control device for motorcycle

A brake interlock determining portion (36) starts a front-wheel brake when input hydraulic pressure by a brake operation (pedal operation) on a rear-wheel becomes equal to or greater than an interlocking brake starting pressure value. A threshold selecting switch (40) allows switching of the interlocking brake starting pressure value between when the ABS is active and when the ABS is inactive. When the ABS is active, a lower pressure value is selected as the interlocking brake starting pressure value. When the ABS is inactive, an upper pressure value is selected as the interlocking brake starting pressure value.
