These are the pins that insert into the bike's axle for the Pit Bull Trailer Restraint System.
Applies to Suzuki V-Strom 1000 ('14-'19), V-Strom 1050 ('20-'21).

Sold the '14 DL1000A last November

I paid less than half what they're currently asking a couple yrs ago
Perfect working order (might be indestructible)

How about $40 USD + shipping? Or make an offer. I have ZERO use for them.
