[kz1000st]

I can't find the notation but I remember reading a few years ago that the Mass RMV had declared the Roketa MC-114 a motorcycle because of the wheels and manual shift.

They're not the only State according to this person.
But, after hunting about a bit, apparently the laws in Indiana say these are classed as motorcycles due to the shift mechanism...which means learner permit, license, registration, insurance, and waiting a long time until the skills test is scheduled.

I keep waiting for NY to figure it out. I've had mine up to an indicated 55 mph on a level stretch. It's also similar to the Cub 50cc which was considered a motorcycle back in the day.
