Crated motorcycles typically measure 4 - 8 pcf and rate class 125 - 175; palletized without a full crate they trend denser.
A motorcycle is dense metal in a very airy shape. A full crate around a 500 lb bike commonly comes out at 4 - 6 pcf (class 175); a tight pallet-and-brace setup with the wheels on can reach 7 - 8 pcf (class 125 or 100).
Worked example. A crated 560 lb motorcycle: 90 × 40 × 50 in, 560 lb. That is 104.2 cu ft and 560 lb → 5.38 pcf → class 175. Run your own numbers →
Drain most of the fuel, disconnect the battery, and compress the forks when strapping. Motorcycles also carry liability weight - many carriers require crating or exclude them entirely, so confirm before you book.
