BSA Damper spring, sidecar (Girling 64544120)
A Girling sidecar damper spring (64544120) for the rear suspension, listed under PN 19-7450.
This is the damper spring listed under Girling part 64544120, catalogued for sidecar duty. It shows up in the swinging arm and rear brake control figures in our records, which puts it in the rear suspension area of the bike, but the catalog entry itself is brief on exactly how it mounts or what it pairs with.

A damper spring like this works alongside the rear suspension units to help control movement, and with a sidecar attached the loads and geometry on that side of the bike change enough that shops spec'd different hardware for it. Beyond that, our record doesn't give us more to go on.
If you're fitting a sidecar and trying to match this up, give us a call and we'll go over what you've got before you order.
