Locking hitch pins provide some level of security for your motorcycle carrier, but they are not foolproof. While a locking pin can secure the carrier's receiver tube to your vehicle, it only protects this single connection point. Many motorcycle carriers, including those from MotoTote, have multiple components, and a determined thief could still unscrew other bolts to detach parts of the carrier.
For better protection, consider additional security measures such as using cable or chain locks to secure your motorcycle directly to the carrier, parking in well-lit, high-traffic areas, and ensuring that your motorcycle is insured. This multi-layered approach provides more effective security than relying solely on a locking hitch pin.
