Welcome to the original and only Official Registry for 1999-2000 Excelsior-Henderson Super X motorcycles...of interest...the list actually started in 1993, as the early Serial Number waiting list! This registry is the largest and most accurate with over 1550 registrations. There are no other official registries.

Once your motorcycle is registered, it is added to the permanent Registry records, and you may update it any time with your private login credentials. If your motorcycle is currently not listed in the registry, then contact us and we will add it to the registry and we will email you the login credentials so you may update and make changes to the registry. Previously, an owner was able to create their own new registry listing, but with the age of international spammers and robots, we have disabled that feature and instead we will create a new registry listing for you.

After Registration, to update your registry using your login credentials, click the Update navigation arrow at left.
