The 2017 Points picture is slightly different. This year, first, second and third take home 20, 17 and 15 points, -1 through the rest of the field. Every racer gets a Rider Bonus based on the total number of racers in that category, at that race. So, the more people you beat at a particular race, the more points that race is worth!
