Does anyone know of a site that has general motorcycle statistics? Like the current number of bikes on the road vs the number like 10-20 years ago. Or just general total sales figures for the past few years. Thanks
You can find registrations along with fatality counts and injury estimates in NHTSA's Traffic Safety Facts 2003 (in PDF; 2003 is the most recent). Table 10 has what you're looking for. Registrations and deaths by state are included in the annual motorcycle fact sheet, which can be found here (also PDF).
