My nearest "VIN inspection" location refused to pass me because the employee looked up the VIN with the NHTSA. I rode over to another VIN inspection station and that employee just entered it into the system with no grievance other than asking why I didn't buy a Harley.

Does your Manufacturer Certificate of Origin say motorcycle, minus the word off-road? Maybe your DMV system there is a little more advanced but as long as you have the right MCO I'm wondering if it's worth trying again at another DMV, in case you ran into an employee who was more vigilant than average.
