1%er's or maybe 1/2%er's. We need a patch with a sidecar on it that reads "1/2%" I think the 1%er is taken and would not want to use it, that might up set the out law bikers. You know what I'm sayin. It is probably even less than 1/2% of motorcyclist drive sidecar rigs, don't think there is any way to know.
My rig is registured as just a motorcycle.
