Table schema:
CREATE TABLE table_name_1 (wins INTEGER, year VARCHAR, team VARCHAR, points VARCHAR, class VARCHAR)

Question: What is the largest amount of wins when there are less than 5 points, the class is 500cc, the team is norton, and the year is more recent than 1955?
SQL: SELECT MAX(wins) FROM table_name_1 WHERE points < 5 AND class = "500cc" AND team = "norton" AND year > 1955
