Motorbikes have brakes, ..... until there is an accident .. then it's "Brake Failure"
lights ,, usuallu a traillight that is "out"
and indicators.... rarley used.. and if they do.. it's left on forquite a while.. usually until nose is pulled out of the mobil screen
oh. don't forget the mirrors . that are often removed. they are "not needed" cause they don't look anyway
