By default, Eloquent excludes all the soft deleted records from query results. But, you can force it to get these records.
To get soft deletes with all other records use following code,
$trashedAndNotTrashed = Motorcycle::withTrashed()->get();
To get only soft deletes use the code given below,
$onlyTrashed = Motorcycle::onlyTrashed()->get();
