Frequently asked questions
How do I find the correct replacement mirror for my BSA B31?
Check the mounting thread size (usually M8 or M10, note Yamaha's left-hand thread on the right side) of your B31. Ensure the mirror has road-legal E-approval.
Why do my motorcycle mirrors vibrate at speed?
Engine vibrations are common on motorcycles. Ensure the mounting bolts on your B31 are tight, or install vibration dampers.
