The cupped washer is used to properly locate the steady rubber when mounting the handlebar mounting eyebolt assembly.
This spare is applicable to Triumph 500, 650, and 750 models along with BSA 650 and 750 models.
Triumph T100 1970, Triumph 650 and 750 twins 1969-1982, Triumph T150, T160 1969-1975, BSA A75 1969-1972, and BSA A65, A70 1971-1972.
