U.S. MOTORCYCLE SALES, 1992-2014: They do a good job over at webbikeworld.com with their annual “US Motorcycle Sales” graph and survey.
The obvious picture is that overall annual motorcycle sales are slowly recovering from a big fall that started going down before the recession and then dramatically fell with the recession.
What this graph does not show is that off-road bikes made the biggest advance in 2013-2014 (10.9%), while dual-purpose and street motorcycles made modest gains at 3% and 3.6% respectively. Only one of the four noted categories represented by this graph was down compared to 2013, and that was scooters.
Total U.S. motorcycle sales were 465,783 for 2013 and 483,526 for 2014, which represents a 3.8% increase.
